Synthesis, Spectroscopic Characterizations, and Biological Evalution of Some Substituted 1-Ethyl-1,4-Dihydro-7-Methyl-4-Oxo-1,8-Naphthyridine-3-Carbohydrazide and their Copper Complexes

Different analogs of 1-ethyl-1, 4-dihydro-7-methyH-4-oxo-1, 8-naphthyridine-3-carbohydrazide ( carbonyl hydrazone derivatives of Nalidixic acid, H 1-10) and their copper complexes have been synthesized from reaction of Nalidixic acid hydrazide with substituted benzaldehyde. These are characterized on the basis of IR spectra, H-1-NMR spectra, Mass spectra, elemental and AAS studies for metals. Copper complexes were prepared from CuCl2.2H(2)O and these ligands, the metal ligand ratio was found to be 1:1 and found to be bidentate. The antibacterial, antifungal and antioxidant activities of these hydrazone ligands and their copper complexes have also been evaluated. Copper complexes possess antibacterial and antifungal activities better than the parent hydrazone ligands while they have better antioxidant activity with DPPH radical than copper complexes. Nalidixic acid have maximum of all biological activities, but H-6 showed slightly better antioxidant activity than Nalidixic acid and other activities were close to it.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 149022-15-1, in my other articles.

The Effect of Electron-Withdrawing Groups on Electron Transporting Silane Derivatives with Wide Energy Gap for Green Electrophosphorescent Devices

Silane derivatives with wide energy gap (approximate to 3.5 eV) containing different electron-withdrawing groups of quinoline and naphthyridine are synthesized and used as the electron transporting materials. The different electron transporting and hole/exciton blocking properties of the silane derivatives are investigated via multilayered structure of organic electrophosphorescent devices by using fac-tris(2-phenylpyridine) iridium (Ir(ppy)(3)) as the phosphorescent emitter. 15.4% of maximum external quantum efficiency (EQE) corresponding to 56.2 cd A(-1) of maximum current efficiency is obtained with a maximum power efficiency of 58.9 lm W-1 by employing di-(4-(1,8-naphthyridin-2-yl) phenyl) diphenylsilane (DNPS) as the electron transporting material, combining with 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline as the hole blocking layer, which is higher than the performance of conventional Alq(3) device. When changing naphthyridine of DNPS to the electron-withdrawing group of quinoline (di-(4-(isoquinolin-4-yl)phenyl) diphenylsilane), only 11.4% of maximum EQE with 41.4 cd A(-1) of maximum current efficiency and 32.5 lm W-1 of a maximum power efficiency is obtained. These indicate that the electron transporting ability increases while the electron-withdrawing group changes from quinoline to naphthyridine, which is also consistent with the calculated reorganization energy.
