Abstract

The ultrafast photophysics of conjugated polymers such as poly(para-phenylene vinylene) (PPV) and its derivatives were studied to understand the nature and mechanisms of formation of the primary photoexcitations in these materials. Detailed knowledge of the photoexcitations is essential for developing optimized optoelectronic devices from these materials. Recent progress on several issues are reported: the nature of the intrinsic photoexcitations and nonlinear decay mechanisms in the PPV family; the use of photoinduced charge transfer in blends and bilayers with C60 to achieve novel nonlinear optical effects; and the spatial extent of the photoinduced charge transfer in these systems.
