Extended hybrid tetrathiafulvalene π-donors with oligothienylenevinylene conjugated spacer groups


  • Presented in part at the “Journées Polymeres Conducteurs' 1994”, September 1994, Strasbourg, France.


Hybrid tetrathiafulvalenes (HTTFs) where the TTF units are linked by thienylenevinylene spacers (see Figure) are reported. It is found that the π donor properties of the materials are improved over analogues with oligothiophene spacers, and that they exhibit a smaller band gap. The evolution of the properties as a function of spacer length and the materials syntheses are discussed.
