Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1762-34-1, is researched, Molecular C12H12N2, about Supramolecular architectures of mononuclear nickel(II) and homobinuclear copper(II) complexes with the 5,5′-dimethyl-2,2′-bipyridine ligand: Syntheses, crystal structures and Hirshfeld surface analyses, the main research direction is nickel copper dimethylbipyridine complex preparation crystal structure; Hirshfeld surface analyses nickel copper dimethylbipyridine complex.Formula: C12H12N2.

Two new compounds based on one mononuclear nickel(II) and one homobinuclear copper(II) complexes resp. and of general formula [Ni(dmbpy)2(CH3COO)]ClO4 (1) and [Cu2(dmbpy)2(CH3COO)3]ClO4 (2) with dmbpy = 5,5′-dimethyl-2,2′-bipyridine, were synthesized by hydrothermal treatment. Both were influenced by the coordinated acetate ion mol. The crystal and mol. structures of (1) and (2) were determined by single crystal x-ray diffraction method and both compounds were addnl. characterized by elemental and TGA, FTIR spectroscopy, powder X-ray diffraction and UV-visible. The mononuclear complex (1) shows a distorted octahedral geometry around the metal ion. However, the copper(II) compound crystallizes as an homobinuclear system, in which each of the metal ions is located into the N2O3 coordination spheres adopting a distorted square pyramidal geometry. In (2) the intramol. distance between two copper atoms is of the order of Cu1-Cu2 = 3.38(2) Å. In both crystals packing of these two complexes, H-bonding, π···π, and C-H···π interactions are operative in forming supramol. motifs. 1 Displays two 1D chains that lead to form R88(42) ring motifs, repetition of which generates a 2D supramol. network. These chains interacts with the neighboring ones via intermol. C-H···π and π···π stacking interactions, giving a 3D-stacking network (2D+1D→3D). Formation of a 2D supramol. sheet in the solid state structure of (2) is facilitated by the C-H···O, C-H···π and π···π interactions (1D+1D→2D). Hirshfeld surface anal. and theor. calculations were carried out on the two compounds C-H···O, C-H··· π and π···π stacking interactions play a paramount role in the stabilization of the supramol. architecture of (1) and (2). In addition, absorption spectra reveal their semi-conductive nature (4.19 eV for (1)·and 4.43 eV for (2)).

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Chemical sensors based on nano-sized lanthanide-grafted periodic mesoporous organosilica hybrid materials, the main research direction is lanthanide grafted periodic mesoporous organosilica hybrid nano sized preparation; chem sensor lanthanide grafted periodic mesoporous organosilica nano sized.Synthetic Route of C12H12N2.

In this work authors introduce the use of nano-sized (50-70 nm) lanthanide-grafted periodic mesoporous organosilicas for both metal ion sensing and solvent sensing. For this study a PMO constructed from the N,N-bis(trimethoxysilylpropyl)-2,6-pyridine dicarboxamide linker and tetra-Et orthosilicate (at a 5 : 95 ratio) was employed. This material was grafted with Eu3+, Tb3+ or a mixture of Eu3+-Tb3+ chloride salts to obtain strongly emitting nano-sized luminescence materials. To further enhance the luminescence properties of the materials two different co-ligands were used – 1,10-phenanthroline (phen) and 5,5′-dimethyl-2,2′-dipyridyl (bpy). The luminescence properties of the developed series of hybrid materials were studied in detail in the solid-state and after dispersing in water. The materials were investigated for their use as ion sensors, with the Eu3+ and Tb3+ phen and bpy co-grafted materials showing selective “”turn on”” fluorescence for Pb2+ and Cr3+ ions (at a 10 ppm concentration of the ions). The Eu3+-Tb3+ co-grafted materials showed solvatochromism and could be used as a solvent sensor to distinguish between protic and aprotic solvents.

Formula: C12H12N2. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Dimeric imidazolium ionic liquids connected by bipyridiyl as a corrosion inhibitor for N80 carbon steel in HCl. Author is Zhang, Juantao; Kong, Minjian; Feng, Jiangtao; Yin, Chengxian; Li, Danping; Fan, Lei; Chen, Qibin; Liu, Honglai.

A new type of the dimeric imidazolium-type amphiphile, BDBCmIB (m = 1, 4 and 8), was synthesized using the bipyridiyl as the spacer, and its inhibition performance and mechanism for the corrosion of N80 carbon steel in 1.0 mol·L-1 HCl were evaluated using chem. and electrochem. measurements, surface analyses and d. functional theory (DFT) calculations Results show that the inhibition efficiency of BDBCmIBs increases with their concentrations and the length of tail chains. BDBC8IB exhibits the best inhibition performance among them and its inhibition efficiency almost exceeds 90% in a wide concentration range from 1.0 × 10-6 to 5.0 × 10-4 mol·L-1 at 25.0 °C, which attains the maximum over 95% at 5.0 × 10-4 mol·L-1. Moreover, three BDBCmIBs all display the high inhibition efficiency at 5.0 × 10-4 mol·L-1, nearly exceeding 90%, in the temperature range from 25.0 to 55.0 °C. As a mixed-type inhibitor, BDBCmIBs can retard both cathodic hydrogen evolution and anodic metal dissolution processes, since BDBCmIB mols. bear the imidazolium-based heterocycle with the electron-donating ability and the bipyridine with the electron-accepting ability, thereby facilitating the formation of a protective film on the surface of N80 carbon steel via electrostatic interactions, coordinated and back-donating bonds. The adsorption of BDBCmIBs obeys the Langmuir isothermal model. Our finding demonstrates that the introduction of the bipyridiyl at the spacer does favor improving the inhibition efficiency of such dimeric imidazolium-type amphiphiles, and meanwhile, the proper increase in the number of carbon atoms in the substituents on the imidazole rings can also enhance the inhibition efficiency.

Cerium-based materials such as ceria are increasingly used in catalytic reactions. We report here the synthesis of the first Ce-based metal-organic layer (MOL), Ce6-BTB, comprising Ce6 secondary building units (SBUs) and 1,3,5-benzenetribenzoate (BTB) linkers, and its functionalization for photocatalytic hydrogen evolution reaction (HER). Ce6-BTB was postsynthetically modified with photosensitizing [(MBA)Ir(ppy)2]Cl or [(MBA)Ru(bpy)2]Cl2 (MBA = 2-(5′-methyl-[2,2′-bipyridin]-5-yl)acetate, ppy = 2-phenylpyridine, bpy = 2,2′-bipyridine) to afford Ce6-BTB-Ir or Ce6-BTB-Ru MOLs, resp. The proximity of photosensitizing ligands and Ce6 SBUs in the MOLs facilitates electron transfer to drive photocatalytic HER under visible light with turnover numbers of 1357 and 484 for Ce6-BTB-Ir and Ce6-BTB-Ru, resp. Photophys. and electrochem. studies revealed a novel dual photoexcitation pathway whereby the excited photosensitizers in the MOL are reductively quenched and then transfer electrons to Ce6 SBUs to generate CeIII centers, which are further photoexcited to CeIII* species for HER.

Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Thermodynamics of the Adsorption of Isomeric Dipyridyls and Their Derivatives from Water-Organic Solutions on HYPERCARB Porous Graphitic Carbon, the main research direction is dipyridyls water acetonitrile methanol isopropanol porous graphitic carbon adsorption.HPLC of Formula: 1762-34-1.

High-performance liquid chromatog. is used under near-equilibrium conditions to study the adsorption of isomeric dipyridyls and their derivatives from water-acetonitrile, water-methanol, and water-isopropanol solutions onto Hypercarb graphite-like carbon material in the region of Henry’s law. It is shown that the possibility of forming strong intramol. C-H-N’-hydrogen bonds in a mol. of 2,2′-dipyridyl or its derivatives strengthens the adsorption bonding of adsorbate mols. and the surface of the graphite-like material due to stabilization of their planar conformation. Destabilizing this intramol. hydrogen bond by adding substituents in different positions of the pyridine rings enhances the specific intermol. interaction between adsorbate mols. and the solvent’s components and distorts the planar conformation of dipyridyls, weakening their retention on the Hypercarb material. Pos. adsorption from the water-organic medium on the carbon adsorbent is observed for all of the investigated dipyridyls, with the exception of 2,2′-dipyridyl-N,N’-dioxide, which is adsorbed weaker than the solvent components. Anomalous medium-property dependences are found for the thermodn. characteristics of the adsorption of dipyridyls on porous graphitic carbon, and are attributed to the predominance of adsorbate-adsorbent π-π interactions over hydrophobic ones and the resolvation of adsorbate mols. with acetonitrile in proportion to lowering the content of water in the bulk solution

This work assessed solvent isotope effects on the photoracemization rate and emission lifetime for [Ru(bpy)3]2+ (bpy = 2,2′-bipyridine) in water. An anal. of the effects of temperature on photoracemization rate and emission lifetime demonstrated that the transition from one enantiomer to the other is unaffected by the isotopic composition of the solvent. Also deactivation from the metal-to-ligand charge-transfer (3MLCT) excited state to the ground state is responsible for the solvent isotope effect on the photoracemization rate. The photoracemization reaction proceeds via a bond-breaking mechanism. In this process, a five-coordinated species produced through breaking of the Ru-N bond in the 3d-d* state undergoes a structural change to produce an achiral five-coordinated species. An anal. of the effect of temperature on emission lifetime, excluding the activation to the 3d-d* state that leads to the structural change, showed that the solvent isotopic composition affects deactivation from the 4th MLCT state.

A series of mononuclear DyIII compounds, [Dy(tmpd)3(4,4′-dmpy)] (1), [Dy(tffb)3(4,4′-dmpy)] (2), [Dy(tffb)3(5,5′-dmpy)] (3), and [Dy(tmpd)3(5,5′-dmpy)] () [tmpd = 4,4,4-trifluoro-1-(4-methoxyphenyl)-1,3-butanedione, tffb = 4,4,4-trifluoro-1-(4-fluorophenyl)-1,3-butanedione, 4,4′-dmpy = 4,4′-dimethyl-2,2′-bipyridyl, and 5,5′-dmpy = 5,5′-dimethyl-2,2′-bipyridyl], have been synthesized by modifying β-diketonate ligands and capping N-donor co-ligands. DyIII ions in 1-4 possess N2O6 octacoordinated environments. Compounds 1 and 2 exhibit distorted trigonal dodecahedron configurations, while 3 and 4 display distorted square antiprismatic configurations. Systematic investigations of the a.c. measurements indicate the different magnetic relaxation dynamics with energy barriers (Ueff) of 66 K (1, 45 cm-1), 189 K, (2, 131 cm-1), 115 K (3, 79 cm-1), and 205 K (4, 142 cm-1). To deeply understand their different magnetic behaviors, the magnetic anisotropies of 1-4 were studied by ab initio calculations From ab initio calculations, the energies of the first excited state (KD1) are consistent with the exptl. Ueff under zero d.c. field. Compound 4 presents the largest Ueff because of the smallest gX,Y and μqTM as well as the most strong axial crystal field parameters (CFPs) among compounds 1-4. The M vs. H data exhibit butterfly-shaped hysteresis loops at 2 K for 1-4. The different coordination geometries, the magnetic dynamics, the electrostatic repulsion, and CFPs result from the different substituent effects of ligands, including the electronic effect, the steric effect, and the positions of substituted groups.

Dey, Nilanjan; Bhattacharjee, Subham; Bhattacharya, Santanu published an article about the compound: 5,5′-Dimethyl-2,2′-bipyridine( cas:1762-34-1,SMILESS:CC1=CN=C(C=C1)C1=NC=C(C)C=C1 ).HPLC of Formula: 1762-34-1. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:1762-34-1) through the article.

Multiresponsive smart optical probe based on p-phenylene vinylene backbone is designed for simultaneous sensing of multiple ions, such as Cu2+, Zn2+ and F- at pH 7.4. A rapid color change from colorless to deep yellow is observed upon addition of both Cu2+ and Zn2+ ion. However, under long UV lamp, the green-colored emission of the probe is specifically quenched in the presence of Cu2+, while Zn2+ induces change in the emission color from green to yellow. On the contrary, F-, unlike Cu2+ and Zn2+, does not render any change in visible color, however, an emission quenching, similar to that of Cu2+ addition, was noticed. The binding of metal ions to the central bipyridine core diminishes the ′conformational flexibility′ and facilitates ′ligand to metal ion′ charge transfer. On the contrary, addition of fluoride triggers the cleavage of silyl ether groups and results in the photo-induced electron transfer from free hydroxyl groups to the core aromatic unit. Thus, we can detect as well as discriminate these three ions (Cu2+, Zn2+ and F-) simultaneously by comparing the resp. output signals. Further, a sustainable strategy has been developed for on-site detection of toxic ions using reusable, low-cost paper strips.
