Abstract

Abstract A series of small-sized model π-conjugated oligomers have been prepared from thienylene and phenylene or dimethyl-or dimethoxy-substituted phenylene units. Crystallographic data for the methoxylated compound show a quasi-planar conformation with a non-covalent S–O interaction. The resulting strong conjugation in the gas phase has also been highlighted by UV/photoelectron spectroscopy and theoretical calculations ( ...
