The presence of a hydrogen bond (H-Bond) network has been proved to impact significantly the efficiency organic light-emitting diode (OLED) devices by promoting molecular orientation and structural anisotropy in thin films. design specific compounds control H-Bond formation an amorphous material, hence improve OLED performances, is needed. A successful example given bi-pyridyl-based family n-ty...

A novel binary compounds as 3-(1,3-diphenyl-1H-pyrazol-4-yl)-2-phenyl-2H-benzo[f]indazole-4,9-dione (10) and fused 2-hydroxy-3-(4-hydroxy-7-methoxy-2-oxo-1,2-dihydroquinolin-3-yl)naphthalene-1,4-dione (7) naphtho[2,3-b]furan-3,4,9(2H)-trione (6) based on lawsone ‘that plays important precursor’ was synthesized by reaction with 1,3-diphenyl-1H-pyrazole-4-carbaldehyde halo-compounds, such 2-chlor...

ABSTRACT. A series of new thiophene derivatives was prepared through nucleophilic substitution reactions the precursor N-(4-substituted-phenyl)-5-(2-chloroacetamido)-4-cyano-3-methylthiophene-2-‎carboxamides 4a and 4b with different sulfur and/or nitrogen reagents (namely; mercaptoacetic acid, 2-mercaptobenzothiazole, 5-(phenylamino)-1,3,4-thiadiazole-2-thiol, 2-mercapto-4,6-dimethylnicotinonit...

The title compound, C(4)H(4)N(6)S(2), was synthesized by the reaction of 3-mercapto-1H-1,2,4-triazole with sodium hydrox-ide in ethanol. The mol-ecule possesses a crystallographically imposed twofold axis. Inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into chains along the c axis.
