Abstract

In our group a large number of polyheteroarylenealkenylenes') with thiophene units were synthesized and their electrical conducting properties studied. In connection with this work, we also became interested in using condensed thiophene systems as units for such polymers'). We therefore prepared the benzo [1, 2-b: 4,541 dithiophene system 4 and two of its derivatives.
