Abstraet--Carbazole units in copolymers can be cross-linked by reaction with a Lewis acid catalyst in methylene chloride. The reaction initially causes gel formation, followed by the development (with BF3. Et20) of a characteristic blue colour. The blue product has been shown to be a cationic dye of

β¦ Synopsis
The kinetics of excimer formation and decay in dilute dichloromethane solutions of poly(Nvinyl carbazole) have been investigated using time-resolved fluorescence spectroscopy. Further evidence for dual excimer formation in this polymer is presented; interconversion of the excimeric states appears to be a significant process at room temperature.

Steady-state and time-resolved fluorescence techniques have been used to study the photophysical behaviors of poly(N-vinyl carbazole), PNVCz and a series of N-vinyl carbazole-methyl acrylate (NVCz-co-MA) copolymers in dilute solution as a function of both NVCz composition and temperature. A kinetic
## Abstract The photoluminescence (PL) of poly __n__βvinyl carbazole (PVK) films formed by solution processing was investigated. PVK films were formed by spincasting onto bare glass or glass covered by films of indium tin oxide (ITO) and poly(3,4βethylenedioxythiophene): poly(styrenesulfonate)ethyl
