Optically induced carbazolyl containing polyethers: Concentration effects

This paper describes the structure and luminescence properties of carbazolyl containing polyethers obtained from two oxirane monomers, i.e. N-[3-(9H-carbazol-9-yl)-2-(oxiran-2-ylmethoxy)propyl]-N-phenylaniline and 9-(oxiran-2-ylmethyl)-9H-carbazole, in the presence of cyclic oligo(potassium glycidoxide) as a macroinitiator. The investigated systems show a deep blue photoluminescence and its intensity depends on polymer concentration in tetrahydrofuran used as the solvent.
