New pyridine based liquid crystalline esters with different terminal chains

The synthesis, structural and mesomorphic characterization of new pyridine-based methyl esters carrying a n-alkoxy chain or 3,7-Dimethyloctyloxy branched group at terminal have been presented. The liquid crystalline properties of the new pyridine-based calamitic molecules have been investigated by polarized optical microscopy and differential scanning calorimetry. New compounds exhibit enantiotropic smectic A mesophase at a variable mesomorphic range depending on alkoxy chain length and branching at terminal. The presence of a branched terminal group in chiral or racemic form gives rise to a sharply increase in mesomorphic range as well as decrease in crystallization points by preserving mesophase type.

Effect of organic ligand on ZnO nanostructures and to investigate the photocatalytic activity under visible light illumination

Controlled morphology of zinc oxide (ZnO) was synthesized by simple hydrothermal method. Morphology and size of ZnO nanostructures was controlled by using pyridine as a passivating agent. Pyridine played a crucial role in modifying the morphological size of ZnO nanostructures. The structural analysis confirms the formation of hexagonal phase of ZnO with good crystalline nature. The elemental and composition analysis confirm the presence of ZnO and the existence of pyridine in the composition. The morphological analysis was performed by field emission scanning electron microscope (FE-SEM), transmission electron microscope (TEM) and high-resolution transmission electron microscope (HR-TEM). The degradation property of organic pollutant was studied under visible light irradiation. Maximum degradation efficiency was observed for 0.6 mL of pyridine sample which disappeared completely after 18 min of irradiation. Furthermore, the degradation property of ZnO was studied by different value of pH, concentration of dye and photocatalyst dosage. The optimum values of solution pH, dye concentration, and photocatalyst dosage was 11, 10 ppm, and 75 mg/L, respectively.

Adding a certain compound to certain chemical reactions, such as: 189005-44-5, 6-Methyl-2-(4-methylphenyl)imidazol[1,2-a]pyridine-3-acetic acid, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, SDS of cas: 189005-44-5, blongs to pyridine-derivatives compound. SDS of cas: 189005-44-5

To a solution of 1 g (0.025 mole) of sodium hydroxide and 40 ml of water 5.6 g (0.02 mole) of [6-methyl-2-(4-methyl-phenyl)-imidazo[1,2-a]pyridine-3-yl]-acetic acid are added, whereupon 2.5 ml (3.6 g, 0.021 mole) of benzyl bromide are added dropwise. The reaction mixture is heated to boiling for an hour and a half, then cooled to room temperature and extracted twice with 50 ml of dichloro methane each. The organic phase is washed with 30 ml of a 10 % sodium hydroxide solution and 50 ml of water, dried over anhydrous sodium sulfate, filtered and evaporated. The oily residue is triturated with petroleum ether. The crystalline product is filtered and washed with petroleum ether. Thus 5.3 g of benzyl-[6-methyl-2-(4-methyl-phenyl)-imidazo[1,2-a]pyridine-3-yl]-acetate are obtained, yield 71.0 %. Mp.: 106 – 107 C.
