A naphtho[2,3-c]thiophene-containing mixed polymer (Figure sows this unit) has been synthesized. Such materials have low band gaps and as a result are of interest for potential application in nonlinear optics. Synthetic details are presented and the propeties of the new material compared with those predicted on the basis of MNDO calculations.
