Highly stable unsymmetrical donor–acceptor oligothiophenes equipped with terminal electron-donating triphenylamine and an electron-withdrawing phenyldicyanovinyl groups have been synthesized. An influence of the length of conjugated oligothiophene π-spacer between the donor and acceptor blocks on solubility, thermal, optical and electrochemical properties of such compounds has been revealed.
