Making Benzotrithiophene Stronger Electron Donors

Xin Guo, Suhao Wang, Volker Enkelmann, Martin Baumgarten, and Klaus Müllen, USA (2012)

A new member of the benzotrithiophene family, benzo[2,1-b:-3,4-b':5,6- c'']trithiophene (3a), and its alkyl substituted derivatives (3b-e) were synthesized and characterized. The photophyscial, electrochemical, thermal, crystallographic, and selfassembly properties of these compounds are described. A highly ordered 1D fiber was obtained from 3a by drop-casting. The high HOMO levels and the coplanarity of these molecules show their potential as organic semiconductors and as donor components in donor-acceptor copolymers.
