The versatility of fourfold Stille coupling to afford oligothiophene-functionalizedtetrathienoanthracene (TTA) and benzene derivatives is described. The influence of the larger, more rigid TTA core on the electronic and structural properties was investigated. Comparative optical and electrochemical studies demonstrate a diminishing HOMO–LUMO gap as the length of the oligothiophene chain increases
