Abstract

Abstract The synthesis, structure, and electronic properties of a series of cross-conjugated p- phenylenevinylidene oligomers with one to four double bonds are reported. The X-ray crystal structure of the compound with two double bonds reveals a nonplanar conformation with torsion angles about the C (phenylene)–C (vinylidene) and C (phenyl)–C (vinylidene) formal single bonds of 39.5 (2) and 30.5 (2), respectively. Admixture of quinoid character ...
