Originální abstrakt
Transient photocurrents in thin films of methyl substituted polyphenylene (MeLPPP) and in phenyl-substituted poly phenylenevinylene type copolymer (PhPPV) were observed upon excitation by a laser flash. The questions of the origin of the optical charge generation and following charge transport in these materials are addressed. It has been argued that the observed current transient is a convolution of time dependent charge carrier generation and their motion. By comparing the field dependent photogeneration yield in MeLPPP and PhPPV, transient absorption and double shot photogeneration, the rate limiting steps for photoionization in studied polymers were identified.
