Abstract
Abstract 3,6-Dimethylthieno[3,2- b ]thiophene ( 1a ) and 3,6-dimethylselenolo[3,2- b ]selenophene ( 1b ) have recently become readily obtainable. Starting from these compounds, their dimers, trimers, and tetramers, in which each thienothiophene unit and selenoloselenophene unit were regularly connected at their α-position, were satisfactorily synthesized and characterized by UV/Vis spectral and CV oxidation potentials data. X-Ray single crystal structure analysis of the dimer of 1b revealed that two selenoloselenophene units are twisted with a large dibedral angle of 69.5° with an s -cis structure.
