Abstract
We present evidence for the localization effect of photogenerated carriers in a regular block copolymer made of alternating sequences of thiophene and phenylene rings due to the presence of energy barriers which confine the excitations, Photoinduced (both in the visible and in the infrared regions) and Raman spectra have been studied in dependence of the degree of polymerization of the chains. They indicate that in a long chain copolymer photoinducedFile in questo prodotto:
