Description
Summary: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 of ZnTTPz processed from solution exhibit p-type semiconducting behaviour in field-effect transistors with low hysteresis and reasonable charge carrier mobility. 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.
