The rigid rod polymers poly(/>-phenylenebenzobisthiazole) and poly(benzobisthiazole-p-phenylenebisvinylene) have been prepared as thin film samples by spin coating Lewis acid complexes from solution and regenerating the uncomplexed polymer by washing with water and drying in vacuo. This approach allows fabrication of films that show well resolved vibronic structure in their linear absorption spectra. In this paper we present results of linear- and electroabsorption spectra. From the latter we are able to deduce the average exciton radius which we find to be 13Åd 15ÅPV. The average change in polarisability accompanying the lowest energy ptical transition is also determined. Comparison of our results is made with previous studies. © 1994, Taylor & Francis Group, LLC.
