Outline of Final Research Achievements

In this project, some functional compounds were developed based on knowledge of fluorescence emission of azobenzenes and azomethines by formation of intramolecular coordination bond between nitrogen and boron atoms. The results are as follows: (1) tuning of fluorescence intensity by changing a substituent on the azobenzene, (2) elucidation of a principle of the fluorescence emission from the azobenzenes, (3) fluorescence emission in various colors from azobenzenes bearing two boryl groups, (4) switching of the fluorescence emission by using proton, electron and cyanide ion, and its application to chemical sensors, and (5) concomitant photochemical properties of both fluorescence and photoisomerization in disilylazobenzenes. The results are important in fundamental chemistry.
