Dithieno[2,3-b;3',2'-d]thiophenes (DTT), having substituted phenyl groups at 3- and 4-carbons, have been synthesized, applying 2,5-diketone ring closure reaction using P4S10. Cyclic voltammetry studies indicated that all the DTTs had the oxidation potentials between 1.19 and 1.70V. Computational calculations displayed positive radical spin densities at C2 positions for DTTs and negative for their dimers.
