POLYMERIC ZINC-BISQUINOLINE BASED SELF-ASSEMBLED LIGHT EMITTING DIODES

摘要

Bifunctional 8,8'-dihydroxy-5,5'-biquinoline (bisquinoline) is reactively self-assembled with diethyl zinc to form a linear coordination polymer. The potential of this method to produce insoluble and intractable structures of controllable supramolecular architecture suitable for semiconducting applications has stimulated an in-depth investigation of the growth mechanism of these polymeric chelates. These films were characterized by FTIR, UV/VIS and photoluminescence spectroscopy. The film growth on glass or indium-tin oxide (ITO) coated substrates was monitored by UV/VIS spectroscopy and ellipsometry. FTIR spectroscopy indicates that the self-assembled films are polymeric in nature. Single layer light emitting diodes exhibited an orange electroluminescence, consistent with the corresponding photoluminescence spectrum.
