Abstract

We report a study of time-resolved photoluminescence (PL) in a cyano-substituted poly(p-phenylenevinylene). We have investigated the effect of excitation and emission wavelength as well as solvent on the FL. We observe evidence of luminescence from both intra-and inter-molecular photoexcitations. We find that the relative amounts of these excitations depend strongly on the excitation wavelength and solvent mixture used. (C) 1998 Published by Elsevier Science B.V.
