- 中文摘要: Aluminum and zinc complexes of 4-substituted 8-hydroxyquinoline were used effectively as emissive materials in light-emitting diodes (LED). The substituents chosen in this study were p-methoxy-2-styryl, p-diethylamino-2-styryl, and naphthalene-2-vinyl groups. Their emission spectra were red-shifted with respect to that of aluminum tris(hydroxylquinolate) (Alq3) as a result of extending their p-conjugation. All complexes formed amorphous glasses, which exhibited high thermal and electrical stability. Typical LED devices were fabricated by mixing the dyes with polyvinylcarbazole and spin-coated to form thin films, which were sandwiched between ITO (indium tin oxide) and a metal electrode. These devices displayed yellow-orange emissions with quantum efficiency ca. 0.4%.
