Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Inorganica Chimica Acta called Near-UV-excitable, green-emitting Tb3+-based complexes, Author is Assuncao, Israel P.; Bredol, Michael; Kasprzycka, Ewa; Kynast, Ulrich H.; Lezhnina, Marina, which mentions a compound: 1762-34-1, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2, Category: benzodioxans.

While numerous Eu3+ complexes are known now that can efficiently be exploited at 350-400 nm excitation range, corresponding green Tb3+ emitter complexes are hard to find. Tb3+ salts of fenamic acid and derivatives thereof are interesting candidates for applications using near-UV excitation: on addnl. co-coordination with e.g. 5,5′-dimethyl-2,2′-bipyridine, excitation maximum at 380 nm, at the same time maintaining high efficiencies, can be accomplished. Such coordination compounds hold the promise of being useful as versatile marker mols. in a variety of soft chem. environments.

Computed Properties of C12H12N2. 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. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about The laser-induced potential jump: A method for rapid electron injection into oxidoreductase enzymes.

Oxidoreductase enzymes often perform technol. useful chem. transformations using abundant metal cofactors with high efficiency under ambient conditions. The understanding of the catalytic mechanism of these enzymes is, however, highly dependent on the availability of well-characterized and optimized time-resolved anal. techniques. We have developed an approach for rapidly injecting electrons into a catalytic system using a photoactivated nanomaterial in combination with a range of redox mediators to produce a potential jump in solution, which then initiates turnover via electron transfer (ET) to the catalyst. The ET events at the nanomaterial-mediator-catalyst interfaces are, however, highly sensitive to the exptl. conditions such as photon flux, relative concentrations of system components, and pH. Here, we present a systematic optimization of these exptl. parameters for a specific catalytic system, namely, [FeFe] hydrogenase from Chlamydomonas reinhardtii (CrHydA1). The developed strategies can, however, be applied in the study of a wide variety of oxidoreductase enzymes. Our potential jump system consists of CdSe/CdS core-shell nanorods as a photosensitizer and a series of substituted bipyridinium salts as mediators with redox potentials in the range from -550 to -670 mV (vs. SHE). With these components, we screened the effect of pH, mediator concentration, protein concentration, photosensitizer concentration, and photon flux on steady-state photoreduction and hydrogen production as well as ET and potential jump efficiency. By manipulating these exptl. conditions, we show the potential of simple modifications to improve the tunability of the potential jump for application to study oxidoreductases.

Two novel binuclear lanthanide complexes, [Ln(3-Cl-4-MOBA)3(5,5′-DM-2,2′-bipy)]2(5,5′-DM-2,2′-bipy) (Ln=Eu(1), Gd(2)), (3-Cl-4-MOBA=3-chloro-4-methoxybenzoate; 5,5′-DM-2,2′-bipy=5,5′-dimethy-2,2′-bipyridine) have been successfully synthesized under hydrothermal conditions. The complexes are characterized by single-crystal X-ray diffraction and elemental anal. Complexes 1 and 2 are isomorphous, and each metal center is eight-coordinated with a distorted square-antiprism coordination geometry. The binuclear units are assembled into 1D, 2D and 3D supramol. structures by weak hydrogen bonds (C-H···O and C-H···Cl) and π-π stacking interactions. Thermal behavior of the complexes 1 and 2 was determined by TG/DSC-FTIR techniques. Heat capacities of the complexes are measured by a DSC instrument in the temperature range of 283.15-393.15K. Based on the heat capacities date, the thermodn. functions (HT-H298.15K) and (ST-S298.15K) were obtained. The activation energy E values of the first decomposition stage for complexes 1 and 2 were calculated by integral iso-conversional nonlinear (NL-INT) method. The fluorescence spectra and lifetime of complex 1 (Eu3+ ion) were studied in depth.

A compound: 1762-34-1, is researched, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2Journal, ChemistrySelect called Addressing Multiple Ions Using Single Optical Probe: Multi-Color Response via Mutually Independent Sensing Pathways, Author is Dey, Nilanjan; Bhattacharjee, Subham; Bhattacharya, Santanu, the main research direction is multiple ion single optical probe sensing emission quenching.Reference of 5,5′-Dimethyl-2,2′-bipyridine.

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.

Application of 1762-34-1. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Four rare earth complexes with chlorinated carboxylic acids and bipyridine ligands: crystal structures, thermal analysis and luminescence properties. Author is Zhou, Meng-xue; Ren, Ning; Zhang, Jian-jun.

Four new complexes were successfully synthesized by solvothermal method or conventional solution method, namely [Ln2(5,5′-DM-2,2′-bipy)2 (3,4-DClBA)6 (H2O)(C2H5OH)](Ln=Sm(1), Eu(2)) and [Ln(5,5′-DM-2,2′-bipy)(3,5-DClBA)3]2 (Ln=Sm(3), Eu(4); 3,4-HDClBA=3,4-dichlorobenzoic acid, 3,5-HDClBA=3,5-dichlorobenzoic acid, 5,5′-DM-2,2′-bipy=5,5′-dimethyl-2,2′-bipyridine).

Quality Control of 5,5′-Dimethyl-2,2′-bipyridine. 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 Group 6 Metal Complexes as Electrocatalysts of CO2 Reduction: Strong Substituent Control of the Reduction Path of [Mo(η3-allyl)(CO)2(x,x’-dimethyl-2,2′-bipyridine)(NCS)] (x = 4-6). Author is Taylor, James O.; Veenstra, Florentine L. P.; Chippindale, Ann M.; Calhorda, Maria Jose; Hartl, Frantisek.

[Mo(η3-allyl)(CO)2(x,x’-dmbipy)(NCS)] (dmbipy = dimethyl-2,2′-bipyridine; x = 4-6) were synthesized and their electrochem. reduction studied using combined cyclic voltammetry (CV) and variable-temperature spectroelectrochem. (IR/UV-visible SEC) in THF and butyronitrile (PrCN), at Au and Pt electrodes. The exptl. results, strongly supported by d. functional theory (DFT) calculations, indicate that the general cathodic path of these Group 6 organometallic complexes is closely related to that of the intensively studied class of Mn tricarbonyl α-diimine complexes, which, themselves, have recently been identified as important smart materials for catalytic CO2 reduction The di-Me substitution on the 2,2′-bipyridine ligand backbone has presented new insights into this emerging class of catalysts. For the 1st time, the 2e- reduced 5-coordinate anions [Mo(η3-allyl)(CO)2(x,x’-dmbipy)]- were directly observed with IR spectroelectrochem. (IR SEC). The role of steric and electronic effects in determining the reduction-induced reactivity was also studied. For the 6,6′-dmbipy, the primary 1e- reduced radical anions exert unusual stability, radically changing the follow-up cathodic path. The 5-coordinate anion [Mo(η3-allyl)(CO)2(6,6′-dmbipy)]- remains stable at low temperature in strongly coordinating butyronitrile and does not undergo dimerization at elevated temperature, in sharp contrast to reactive [Mo(η3-allyl)(CO)2(4,4′-dmbipy)]- that tends to dimerize in a reaction with the parent complex. The complex with the 5,5′-dmbipy ligand combines both types of reactivity. Under aprotic conditions, the different properties of [Mo(η3-allyl)(CO)2(x,x’-dmbipy)]- are also reflected in their reactivity toward CO2. Preliminary CV and IR SEC results reveal differences in the strength of CO2 coordination at the free axial position. Catalytic waves attributed to the generation of the 5-coordinate anions were observed using CV, but only a modest catalytic performance toward the production of formate was demonstrated by IR SEC. For 6,6′-dmbipy, a stronger catalytic effect was observed for the Au cathode, compared to Pt.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Russian Journal of Physical Chemistry A called Thermodynamics of the Adsorption of Isomeric Dipyridyls and Their Derivatives from Water-Organic Solutions on HYPERCARB Porous Graphitic Carbon, Author is Saifutdinov, B. R.; Buryak, A. K., which mentions a compound: 1762-34-1, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2, Computed Properties of C12H12N2.

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
