| Research Abstract |
Helical poly(L-glutamate) with carbazole(Cz) side chains(PCELG) was synthesized as a hole-transport material for a dye-doped polymer electroluminescence(EL) device. For green and blue light, EL devices using PCELG(PCELG device) was found to exhibit luminance efficiencies comparable to those using poly(N-vinyl carbazole)(PVK). The maximal efficiencies of PCELG devices strongly depend on the casting solvents used during the film-forming process, which amount to the 20 times at the maximum. We pointed out that the solvent dependence of PCELG device attributed to the aggregation structure of PCELG chain at around the interface of the emitter layer/ITO electrode from the ellipsometric analysis.
