• The singlet-energy transfer from the phenol to the indole chromophores occurs intramolecularly, with a high efficiency, in the compounds containing these chromophores joined by the methylene and the amide groups. The total emission spectra of the compounds consisted only of those from the indole chromophore, neither the fluorescence nor the phosphorescence of the phenol chromophore contributing to them, and the excitation spectra of the fluorescence were similar to the absorption spectra. The quantitative analysis of the fluorescence-polarization spectra suggested that the <SUP>1</SUP>L<SUB>b</SUB> transition of the indole chromophore was excited in the energy transfer. The intramolecular interactions between these chromophores in the ground and excited states are discussed.
