Four monomers, viz., w-(9-carbazolyl)alkyl methacrylates, were prepared from 9-(w-bromoalkyl)carbazoles and alkali metal salts of methacrylic acid. The methacrylates were polymerized in toluene by using azobisisobutyronitrile (AIBN) as initiator. Molecular weights of the resulting polymers were established by gel permeation chromatography (GPC) (Table 2). Photoluminescence spectra were recorded for the four synthesized polymers in the solid state and for poly(vinyl carbazole). The spectra were found to be comparable, the intensity of emission was found to be related to the number of carbon atoms in the alkyl chain (C2—C6) and to increase as the length of the chain was increased.

Keywords: w-(9-carbazolyl)alkyl methacrylates, radical polymerization, photoluminescence spectra.
