Abstract

In recent years, the promising prospects for applications of polymers in optoelectronic and nonlinear optical devices have stimulated much interest in their fundamental optical properties. Among the attractive polymers for electroluminescent devices are poly(phenylenevinylene)(PPV) and poly(phenyl-p-phenylenevinylene) (PPPV). Although high quantum yields are demonstrated [1], several fundamental properties like the large Stokes shift between absorption and luminescence are not well understood. For an optimization of material parameters, a detailed understanding of the optical response is needed.
