Electron transporting and hole blocking organic material and application thereof in thin-film light-emitting diode

The invention provides an electron transporting and hole blocking material with an A-D-A link structure as a core. The material is applied to a thin-film semiconductor light-emitting diode, for example, an organic light-emitting diode and a quantum dot thin-film light-emitting diode; and the molecule of the material takes bipolar carbazole and a derivative group thereof as electron donating centers, so a relatively high triplet state energy level can be maintained to ensure exciton blocking capability.

Synthesis and characterization of 2-phenylpyrazoline derivatives and evaluation of their activities against antimicrobial and breast cancer cell line in vitro and in silico studies

The new series of 2-phenylpyrazoline derivatives (2a-j) were synthesized and evaluated for their antimicrobial, in silico and in vitro anticancer activity was performed by MTT assay using MDA-MB-231 (human breast adenocarcinoma) cell line. The 2-phenylpyr

An efficient synthesis and in vitro antimicrobial screening of 2-cyanoimino-4-aryl-6-(1,1′-biphenyl-4-yl)-3, 4-dihydro-1H-pyrimidines

An efficient synthesis of 2-Cyanoimino-4-aryl-6-(1,1′-biphenyl-4-yl)-3,4-dihydro-1H-pyrimidines from stryl-4-biphenylketones and cyanoguanidine in presence of sodium hydroxide has been described. Cyanoguanidine serves as N-C=N source for the construction of desired cyanoiminopyrimidines. The structural assignments of the titled products were done accordingly to their spectra like Mass, FT-IR, Proton and Carbon-13NMR spectroscopy. The more stable tautomeric form was ascertained using computational frequency analysis. The tested microorganism profile of compounds exhibits significant antimicrobial activity.

Solvent free synthesis of different substituted pyrazoles under microwave irradiation via one pot synthesis and their biological evaluation

Pyrazoles and their derivative are widely used as pharmaceutical and agrochemical agents and consequently a large number of synthetic routes to pyrazole have been reported. Due to the property of reducing blood sugar by pyrazole, it has resulted in the sy
