the macrocyclic ligands 2,3,5,6-bis{3’-bromo-5’-tert-butyl benzo-5-phenyl benzo} 12c3 (l1), 2,3,5,6-bis{3’-bromo-5’-tert butyl-benzo-5’-phenyl-benzo}15c4 (l2), 2,3,5,6-bis{3’-bromo-5’-tert butyl-benzo-5’-phenyl-benzo}18c5 (l3) have been synthesized and their alkaline metal compounds with naclo4∙h2o and kclo4  have been prepared. chemical formulas of all compounds have been characterized by usin...

Catalytic and photocatalytic reactions of (2-chloroethyl) phenyl sulfide (2-CEPS), a mimic of bis (2-chloroethyl)  sulfide (i.e. Sulfur mustard) were studied on the surfaces of titanium oxide. TiO2 nanoparticles (anatase, rutile and mixture of 80% anatase/20% rutile) along with bulk TiO2 were tested as reactive sorbents for reaction of 2-CEPS at room temperature (25±0.5°C). Reactions were monit...

This study presented the effects of carrier-transporting layer (CTL) on electroluminescence (EL) performance a blue phosphorescent organic light-emitting diodes (PHOLEDs) with electron transporting host based three kinds electron-transporting layers (ETLs) including 3-(4-biphenyl-yl)-4-phenyl-5-(4-tert-butylphenyl)-1,2,4-triazole (TAZ), diphenyl-bis[4-(pyridin-3-yl)phenyl]silane (DPPS) and 1,3,...

The title zinc bis(thiosemicarbazone) complex, [Zn(C 22 H 17 N 4 O 2 S) ], comprises two , S -donor anions, leading to a distorted tetrahedral donor set. resultant five-membered chelate rings are nearly planar and form dihedral angle of 73.28 (3)°. configurations about the endocyclic- exocyclic-imine bonds Z E respectively, that ethylene bond is . major differences in conformations ligands seen...

a new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. the synthesised compounds have been screened in vitro for their antimicrobial acti...
