Abstract :
In the present work the photoconductivity of two different polyparacyclophanes doped with 2,4,7-trinitrofluorenone (TNF) was investigated by means of surface potential discharge method. The photogeneration quantum yield is compared with the results for the poly(N-vinylcarbazole) (PVK) pure and doped with TNF and the field dependences of the photogeneration yield are analyzed using the Onsager and the Braun models
