| Outline of Final Research Achievements |
Aiming at the analytical applications in the field of biochemistry, functional fluorescent dyes were synthesized based on naturally occurring (bacterio)chlorophylls. 1) The synthetic C3-ureidochlorin showed fluorescence emission spectral responses with the addition of anions in dichloromethane, 2) a series of carboxylated chlorins were synthesized and the detection of additional amine in THF was demonstrated by both visible absorption and fluorescence emission spectroscopies, 3) the selective detection of histidine was demonstrated using monomeric/oligomeric zinc chlorins in an aqueous buffer solution, and 4) bacteriochlorophyll-a derivatives possessing different substituents at the C13-position were synthesized, which showed fluorescence emission maxima in the longer wavelength region (>800nm).
