Abstract

Abstract : The synthesis of the first soluble thieno[3, 2- b ]thiophene based porphyrazine (ZnTTPz ) is reported from the cyclisation of 2, 3-dicyano-5-octylthieno[3, 2- b ]thiophene. Abstract : The synthesis of the first soluble thieno[3, 2- b ]thiophene based porphyrazine (ZnTTPz ) is reported from the cyclisation of 2, 3-dicyano-5-octylthieno[3, 2- b ]thiophene.ZnTTPz can be considered the all thiophene analogue of naphthalocyanine.ZnTTPz exhibits a red-shifted absorption in solution and thin film, as well as a reduced band gap in comparison to the thiophene analogue due to an increased conjugation length. Films ofZnTTPz processed from solution exhibit p-type semiconducting behaviour in field-effect transistors with low hysteresis and reasonable charge carrier mobility.
