Abstract

In the reported experiments, formation processes of poly(N-vinylcarbazole) cation (PVCZ** plus ) and its reactivity were studied by a pulse radiolysis technique. In the formation of PVCZ** plus , the charge transfer from a solvent or additive cation radical plays an important role. Once formed, the PVCZ** plus is stabilized. This stabilization makes the ion recombination reaction rate smaller by a factor of about 5 compared with the monomer cation. The cation scavenging reaction is also affected by this stabilization, and PVCZ** plus is only scavenged by certain compounds of appreciably low ionization potential (for example; N,N,N prime ,N prime -tetramethylbenzidine). The rate constant for the scavenging reaction was estimated to be about 3 multiplied by 10**9 M** minus **1 s** minus **1.
