Outline of Final Research Achievements

It is difficult to achieve the practical use of porphyrin J aggregates are difficult because the porphyrin J aggregates can be formed under specific conditions or by using the porphyrin derivatives with complicated structures. In this study, we could prepare the porphyrin J-aggregate easily using the porphyrin with a simple structure in ionic liquids. In order to construct the efficient light energy using system, fluorescence resonance energy transfer and aggregation-induced emission between porphyrin-ionic liquids were observed. In addition, we synthesized fluorescent ionic liquids with fluorophores so that the ionic liquids were used as effective fluorescent donors. Ionic liquids also have high ion conductivities. Thus, such techniques that we reported in this project can be applied to photochemical materials and photoelectric-conversion systems.
