Luminescence properties of novel substrituted polyethers

摘要

New polyethers have been obtained in the anionic polymerization of oxiranes containing carbazole and/or hydrazone groups in the substituent. Excitation and luminescence spectra of the novel polymers were measured in powder and in tetrahydrofuran solution. It allowed to conclude that in the absence of excimer trapping sites, only intermolecular energy migration will be encouraged in dilute solutions of the polymers. Some polyethers and their solutions in tetrahydrofuran showed blue fluorescence. That would have an application to electroluminescent materials, such as electroluminescence polymer diodes.
