2,5-Bis(2,2-diphenylethenyl)thiophene

Abstract

The ethene units of the title compound, C32H24S, a possible candidate for Organic Light‐Emitting Devices, are tilted with respect to the thio­phene unit by 6.2 (1) and 9.2 (1)°.

Bis(imidazolium) tetrachlorocobaltate(II)

“…A methylene-bridged bis(imidazolium) salt, (C 9 H 14 N 4 )-[CoCl 4 ], containing a tetrachlorocobaltate(II) anion, has been described recently (Zeller et al, 2005). In the related title compound, (I) ( Fig.…”

Synthesis and structures of substituted triphenyl(phenylimino)phosphoranes

“…The solid-state structures and electronic properties of one particular class of these oligomeric organic semiconductors, viz. distyrylbenzenes, oligomeric derivatives of PPV [poly(pphenylene vinylene)], have already been extensively studied and the influence of substituents on the properties of the carbon backbone have been investigated (Baeke et al, 2007;Vande Velde et al, 2004;Vande Velde, Baeke et al 2005;Vande Velde, De Borger et al, 2005;Vande Velde et al, 2006;Irngartinger et al, 1994;Hakansson et al, 1992;Bartholomew et al, 2000a,b;Coates et al, 1998;Nohra et al, 2006;Renak et al, 1999;Sancho-Garcia et al, 2005;Zeller et al, 2005). However, keeping in mind the tunability of these materials, it is equally interesting to determine the effects of the replacement of the ethenylic -CH CH-link by other spacers such as -CH N-…”

Ionothermal synthesis and crystal structure of a new organic–inorganic hybrid compound:catena-poly[bis(1-ethyl-3-methylimidazolium) [hepta-μ-bromido-pentacuprate(I)]]

“…The introduction of organic molecules in the synthesis of polynuclear copper(I) halides is the most extensively and effectively employed strategy to modulate copper(I) halide structures (Xin et al, 2013). Only a few reports of the solidstate structures of imidazolium salts containing transition metals and halide anions have been published (Zeller et al, 2005;Chen et al, 2011;Ji et al, 2011;Hu et al, 2011;Shao & Yu, 2014). They all show short contacts between the halide atoms of the cuprate(I) anion and the H atoms of the 1-ethyl-3-methylimidazolium (emim) cation.…”
