Synthesis and characterisation of new diindenodithienothiophene (DITT) based materials
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 cm 2 V -1 s -1.

Abstract

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 cm 2 V -1 s -1.
