The article 《Construction of lanthanide complexes based on 3,4-dichlorobenzoic acid and 5,5′-dimethyl-2,2′-bipyridine: Supramolecular structures, thermodynamic properties and luminescent behaviors》 in relation to this compound, is published in Polyhedron. Let’s take a look at the latest research on this compound (cas:1762-34-1).

Two novel lanthanide complexes, [Ln2(3,4-DClBA)6(5,5′-DM-2,2′-bipy)2(C2H5OH)(H2O)] (Ln = Gd (1), Tb (2)); 3,4-DClBA: 3,4-dichlorobenzoate; 5,5′-DM-2,2′-bipy: 5,5′-dimethyl-2,2′-bipyridine have been hydrothermally synthesized and structurally characterized by elemental anal., IR spectrum, thermal anal. and single x-ray diffraction techniques. The binuclear complexes 1-2 are isomorphous and crystallize in the triclinic crystal system and P1̅ space group, and each metal center is eight-coordinated with distorted square antiprismatic mol. geometry. The structure of this type of complex is unique in that the solvent ethanol mol. participates in the coordination. Complexes 1-2 are stitched together via π-π stacking interactions and hydrogen bonding interactions to form the 1D, 2D supramol. structures. The thermal decomposition mechanisms of two complexes were obtained by TG-DSC/FTIR techniques. The molar heat capacities of the complexes 1 and 2 are measured by a DSC instrument over the temperature range from 255.15 to 323.15 K and thermodn. functions were calculated by fitted polynomial and thermodn. equations. The luminescence studies demonstrate that complex 2 exhibits the characteristic emission of Tb3+ ion (5D4 → 7F6-3).

SDS of cas: 1762-34-1. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Stable Radical Cation-Containing Covalent Organic Frameworks Exhibiting Remarkable Structure-Enhanced Photothermal Conversion. Author is Mi, Zhen; Yang, Peng; Wang, Rong; Unruangsri, Junjuda; Yang, Wuli; Wang, Changchun; Guo, Jia.

The production of a radical cation-containing covalent organic framework (COF) has been accomplished by sequential in situ reactions, quaternization, and one-electron reduction of the 2,2′-bipyridine-based COFs. The acid-catalyzed COF formation enables the cis configuration of 2,2′-bipyridyl moieties in the structure, of which the stability arises from the eclipsed stacking of the two-dimensional layered structure. The postfunctionalization generates cyclic alkylated diquats as the sole products from the controlled quaternization. The reduction of diquat cations on the COF skeletons results in a large number of radical cations, which delocalize and uniaxially stack on top of one another by virtue of interlayered π-electronic couplings. The absorption of the near-IR (NIR) region exhibited by the cationic radical COF is remarkably high owing to the intercharge transfer across the π-coupling interlayers. Also, the long-range array of extended and planar frameworks in such a COF leads to the extra stability of the radical cations against external stresses. The structure-enhanced performance of the COF material is witnessed with photothermal conversion efficiencies of as high as 63.8 and 55.2% when exposed to 808 and 1064 nm lasers, resp. Further PEG modification on such a COF allows photoacoustic imaging and photothermal therapy in vivo under NIR light illumination to be manifested.

Product Details of 1762-34-1. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate.

Author is Pan, Yao; Zhang, Nan; Liu, Chun-Hua; Fan, Shilu; Guo, Song; Zhang, Zhi-Ming; Zhu, Yuan-Yuan.

The merger of photocatalysis and transition-metal catalysis is of particular interest to develop useful and challenging synthetic methodologies. The catalytic activities of conventional dual-catalytic systems, however, are limited by the low synergistic efficiency between discrete catalytic centers due to their long average distance in solution Herein we carefully decorated Ir(III) photosensitizers and Ni(II) transition-metal catalyst into flexible polymers to afford two polymer-supported dual catalysts (P1-Ni and P2-Ni). These polyelectrolyte-type metallopolymers assembled into spherical polymer particles in some polar solvents. Their unique mol. and assembled structure contributed to shortening the distance between catalytic centers and increasing the local catalysts′ concentration within the catalyst, thereby greatly facilitating their electron, energy, and organic radical transfers during the catalytic cycles. The enhanced energy interaction and matched redox potential between two catalytic centers within the polymer were confirmed by steady- and transient-state luminescent spectra and cyclic voltammetry. These features enable them in catalyzing challenging organic transformations that involve efficiently incorporated photocatalytic and transition-metal catalytic cycles. We demonstrated that these two catalysts were highly effective in catalyzing C-S cross-coupling, C-O functionalized, C-N cross-coupling, and C-C cross-coupling reactions with broad substrate scopes and low catalyst loadings with turnover numbers of ~3100, ~1500, ~1400, and ~500, resp. This work provides a general methodol. to merge photosensitizer and transition-metal catalyst in a flexible polymer for significantly boosting the catalytic activity.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Dual Cobalt and Photoredox Catalysis Enabled Redox-Neutral Annulation of 2-Propynolphenols, published in 2021-07-01, which mentions a compound: 1762-34-1, Name is 5,5′-Dimethyl-2,2′-bipyridine, Molecular C12H12N2, Quality Control of 5,5′-Dimethyl-2,2′-bipyridine.

A hydroxyl-assisted, organophotoredox/cobalt dual catalyzed annulation of 2-propynolphenols I [R1 = H, R2 = H, F, Cl, Br, MeO2C, Me; R1 = Cl, R2 = H; R1 = R2 = F; R3 = R4 = Me, Ph, 4-FC6H4, 3-F3CC6H4, etc.; R3 = Ph, R4 = Me, 4-ClC6H4, 2-FC6H4, 4-F3CC6H4, 2-thienyl, etc.; R3 = 4-FC6H4, R4 = 4-MeOC6H4; R3R4 = (CH2)5] to form 2-(hydroxymethyl)benzo[b]furans II has been developed by employing 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN) as photosensitizer and CoCl2(PPh3)2/5,5′-dimethyl-2,2′-bipyridine as cobalt catalytic precursor. Various substrates and functional groups were tolerated. The practical applications of this reaction were further demonstrated by enlarged gram-scale and various derivations for complex heterocycles.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Asahara, Masahiro; Kurimoto, Haruhiko; Nakamizu, Masato; Hattori, Shingo; Shinozaki, Kazuteru researched the compound: 5,5′-Dimethyl-2,2′-bipyridine( cas:1762-34-1 ).Recommanded Product: 5,5′-Dimethyl-2,2′-bipyridine.They published the article 《H/D solvent isotope effects on the photoracemization reaction of enantiomeric the tris(2,2′-bipyridine)ruthenium(II) complex and its analogues》 about this compound( cas:1762-34-1 ) in Physical Chemistry Chemical Physics. Keywords: preparation ruthenium bipyridine phenanthroline complex; solvent isotope effect ruthenium bipyridine phenanthroline complex; photoracemization reaction ruthenium bipyridine phenanthroline complex. We’ll tell you more about this compound (cas:1762-34-1).

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.

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 Synthesis and Acid-Responsive Properties of a Highly Porous Vinylene-Linked Covalent Organic Framework, the main research direction is acid responsive porous vinylene covalent organic framework; Hill equation; acid response; acidochromic; covalent organic framework; fluorescence; gas sensor.Reference of 5,5′-Dimethyl-2,2′-bipyridine.

The recently emerging vinylene-linked covalent organic frameworks (VCOFs) stand out from other COFs with exceptional chem. stability and favorable light-emitting properties, promising sensing applications for acids/bases or in strong acidic/basic conditions. Here we systematically investigated the reversible color and fluorescent response of a VCOF functionalized with pyridyl groups to acids/pH. The COF was synthesized with a record surface area for VCOFs and shows reversible hydrochromic and acidochromic behaviors and concomitant fluorescence quenching. The mechanisms were probed with systematical exptl. comparison with relevant COFs and model mols. in combination with orbital anal. The response is related to significant electronic changes in the ground and photoexcited states as a result of protonation or hydrogen bonding at pyridyl sites. The COF in aqueous dispersion displays a reversible fluorescence transition with pH change, which follows the Hill equation for multisite protonation. The COF-modified test paper shows immediate and remarkable color change and fluorescence turn-off/on when alternately exposed to HCl and NH3 gases. The work illustrates the great potential of developing highly robust sensory COFs through the vinylene approach.

Formula: C12H12N2. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Multimode Self-Oscillating Vesicle Transformers. Author is Shao, Qing; Zhang, Shaodong; Hu, Zhen; Zhou, Yongfeng.

Engineering synthetic materials that mimic the complex rhythmic oscillatory behavior of living cells is a fundamental challenge in science and technol. Up to now, the reported synthetic model system still cannot compete with nature in oscillatory modes and amplitudes. Presented here is a novel alternating copolymer vesicle that exhibits drastic and multimode shape oscillations in real time, which are controlled by polymer concentrations and driven by the Belousov-Zhabotinsky oscillatory reaction, including swelling/deswelling, twisting/detwisting, stretching/shrinking, fusion/fission, and multiple division. Some of them, especially the fission oscillation, have not been observed before. In addition, the oscillation magnitude with regard to diameter is much larger than that of previously reported self-oscillating vesicles. Such a self-oscillating vesicle transformer would extend the complexity and capacity of membrane deformations in synthetic systems, approaching those of natural cells.

The size of N-N ligand and its substituents modulate the compound electronic features and influence their antiproliferative efficiency against Entamoeba histolytica, 56dmphen derivative, shows the biggest molar volume and presents a powerful amoebicidal activity (IC50 = 1.2μM), being seven times more effective than the first-line drug for human amoebiasis metronidazole. Also, increases the reactive oxygen species concentration within the trophozoites. This could be the trigger of the E. histolytica growth inhibition. The antiparasitic effect is described using NiII electron d., molar volume, estimated by DFT, as well as the exptl. redox potential and diffusion coefficients In general, amoebicidal efficiency is directly proportional to the increment of the molar volume and decreases when the redox potential becomes more pos.
