Research Abstract

Studies on photo-functional interfaces are very important for the progress of photo-energy conversion and photocatalysts, and for the creation of novel functional materials. At the interfaces, which are formed between different materials, nanometer-scale structural control plays important roles for the appearance of physical properties and functionalities. In this study, molecular systems with ordered nano-structures were investigated as a material to control interfacial properties. In order to apply them as devices by constructing novel molecular assemblies which exhibit photo-functions and electronic functions, following studies were performed : (1) design of exciton-controlling materials by controlling nano-structures of porphyrin J-aggregates, (2) spin alignment of π-radicals of porphyrin arrays on the basis of nano-structural controlling, (3) formation of J-aggregates at the surface of titania and development of materials with electronic spin-functions derived from interfacial ele … More ctron transfer, and (4) development of energy-storable dye-sensitized solar-cells. In this study, it was found that protonated water-insoluble porphyrin derivatives are self-assembled at interface to form J-aggregates, and their association structure and excitonic interaction could be changed variously. It is large progress that efficient excitation energy transfer was observed at hetero-layered nano-sheets of porphyrin J-aggregates, which were developed in this study. On the other hand, multiplet spin states were achieved in this study by generating the π-radicals of directly-linked porphyrin arrays, indicating that spin-spin interactions can be modified by controlling the nano-structures. The result is important for molecular magnetism or development of magnetic functional materials. Furthermore, we have developed the fundamental structure of energy-storable dye-sensitized solar-cell, which is important breakthrough to achieve stable outputs and low costs, and is expected to contribute the propagation of solar-cells.
