This project was conducted toward efficient electrophosphorescence devices combined with a self-organized superlattice materials, lead halide-based layered peorvksite, and organic semiconductors. The results of this project are summarized as follows.1.From transient photoluminescence measurement for lead bromide-based layered perovskites, which were prepared with aminoalkylnaphthalenes, enhance phosphorescence due to naphthalene chromophore in the layered perovskite was demonstrated to be caused by efficient energy transfer (Dexter-type) from exciton in the lead bromide semiconductor layer to, triplet excited state of the naphthalene chromophore.2.The following new layered perovskites were successfully prepared, layered perovskites having 1)bifunctional chromophore combined triplet-sensitized benzophenone choromophore and emissive chromophore, 2)hole-transporting and emissive carbazole chromophore, and 3)p-conjugated polymers. Further, phosphorescence was observed in the new layered perovskites.3.We successfully prepared lead halide-based layered perovskite thin films with emissive chromophores by using the Langmuir-Blodgett technique.4.Electro phosphorescence was successfully observed in the try-layered device combined with the phosphorescent layered perovskite, electron-transporting oxadiazole, and hole-transporting copper phthalocyanine.5.We found new organic-inorganic nanohybride as emissive material. The nanohybride was prepared by simaultaneous deposition. of organic semiconductor and rare-earth metal. In organic electroluminescent device using the nanohybrids, fairly efficient blue, green, red electoroluminescence was observed.
