Abstract

A laser photolysis method, monitoring transient absorption under total internal reflection condition, was developed and applied to poly(N-vinylcarbazole) thin films. Photoinduced charge separation was confirmed directly for polymer films doped with some electron acceptors. Absorption spectra composed of polymer cation and acceptor anion are ascribed to migrating hole and trapped electron, respectively, and their decay curves correspond to a homogeneous recombination process.
