| Research Abstract |
With the aim to develop novel light-emissive materials, synthesis of fluorescent organosilicon compounds and elucidation of emission mechanism were studied. As a result, aromatic rings and substituents on silicon atoms, and number of arylethynyl groups and acetylene linkages, are important for design of fluorescent organosilicon compounds, and it was demonstrated that fluorescence wavelengths, intensities, and lifetimes can be controlled by their molecular structures. Development of light-emissive molecules whose color of emission changed depending on surrounding environments, development of molecules that exhibit only intramolecular excimer emissions, and preparation of light-emissive PMMA films were also achieved.
