Three new diindenodithienothiophene (DITT) based materials were synthesised and their electrochemical properties investigated. The HOMO–LUMO gaps were observed to be 3.33, 3.48 and 2.81 eV, respectively. Cyclic voltammetry results indicate increased stability for the alkylated derivatives. The dioxide exhibits strong photoluminescence, giving a photoluminescence quantum yield of 0.72 in solution and 0.14 in the solid state. Hole mobility measurements were carried out on the non-alkylated derivative and the corresponding values were ∼10−4 cm2 V−1 s−1.
