Outline of Final Research Achievements

Development of new functional fluorescent sensors by using highly emissive organosilicon compounds were studied. When silyl and silylethynyl groups are introduced to stilbene, phenanthrene, and pyrene, fluorescence wavelengths shifted to longer wavelength regions, and fluorencence quantum yields increased. Monomer and intramolecular excimer emissions of pyrene in (1,3), (1,8), and (1,6)pyrenophanes were reversibly changed depending on addition of metal ions and ammonium salts, solvents, and temperature. Several ON-OFF fluorescent sensor molecules based on reversible photochemical reactions of aromatic groups and alkenes were also developed.
