Abstract
Alkoxy-substituted thiophenes have been shown to yield polymers with a reduced bandgap. An X-ray investigation of two symmetrical pentoxy-su bstituted 2,2'-bithienyls is reported, and their structure and packing described. It is suggested that the extra rigidity and packing stabil ity of the alkoxythiophene oligomers and polymers accounts for their l ower solubility and higher melting points compared to their alkyl-subs tituted analogues.
