What is "n-vinylcarbazole"

N-Vinylcarbazole is an organic compound used as a monomer in the production of poly(vinylcarbazole), a conductive polymer, in which conductivity is photon-dependent. The compound is used in the photoreceptors of photocopiers. Upon exposure to γ-irradiation, N-vinylcarbazole undergoes solid-state polymerisation.
