A series of new tetrasubstituted imidazoles 2-phenyl-3-(1, 4, 5-triphenyl-1H-imidazol-2-yl)-1H-indole derivatives substituted with –F, Cl, Br, I,-OCH3 and -NHCOCH3 were synthesized using a multicomponent reaction. The compounds were obtained in good yields by easy workup and with high purity

The title complex, [Cu(3)WBrOS(3)(C(18)H(15)P)(3)], a neutral heavily distorted cubane-like W/S/Cu cluster, was self-assembled from ammonium trithio-tungstate(VI), cuprous bromide and triphenyl-phosphane in N,N-dimethyl-formamide. The average Cu-Br, Cu-S and W-μ(3)-S bond lengths are 2.731 (2), 2.318 (2) and 2.256 (2) Å, respectively, in the distorted cubane-like skeleton. The W atom exhibits t...

Perylene bisimide and triphenyl diamine are prototypical organic dyes frequently used in organic solar cells and light emitting devices. Recent Forster-resonant-energy-transfer experiments on a bridged organic dyad consisting of triphenyl diamine as an energy-donor and perylene bisimide as an energy-acceptor revealed a strong fluorescence quenching on the perylene bisimide. This quenching is ab...

The asymmetric unit of the title mol-ecular salt, C(19)H(15)N(4) (+)·I(-), contains four 2,3,5-triphenyl-2H-tetra-zol-3-ium cations and five iodide anions, with two of the latter lying on crystallographic inversion centres. In each cation, the tetra-zole ring is essentially planar (r.m.s. deviations = 0.004-0.007 Å). The dihedral angles between the tetra-zole ring and its three attached benzene...

The six-membered thio-pyran ring in the title compound, C(26)H(24)S, adopts a boat conformation, with the S atom displaced by 0.478 (2) Å and the 3-methyl-ene C atom by 0.644 (2) Å from the plane of the other four sp(2)-hydridized C atoms. The methyl group on the methyl-ene carbon lies in a pseudo-equatorial position and the phenyl ring in a pseudo-axial position.
