Outline of Final Research Achievements

N-Silylethynylcarbazoles have been synthesized. The fluorescent spectra of these compounds showed excimer emission. Ethynyldibenzosilole, in which the dibenzosilole unit is utilized as an acceptor, has been also synthesized. By coupled with various iodoarenes, donor-acceptor dyes have ben synthesized. These dyes also showed the excimer emissions. As described, each module bearing donor unit or acceptor unit with ethynylene spacer have been successfully synthesized. These modules have been proved to be applicable for synthesis of various dyes.
