Abstract

Formation processes of poly(N-vinylcarbazole) cation (PVCZ+) and its reactivity were studied by a pulse radiolysis technique. In the formation of PVCZ+, the charge transfer from a solvent or additive cation radical plays an important role. Once formed, the PVCZ+ 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+ is only scavenged by certain compounds of appreciably low ionization potential (for example; N, N, N′, N′-tetramethylbenzidine). The rate constant for the scavenging reaction was estimated to be about 3×109 M−1 s−1.
