1-ナフチルアラニルグリシン誘導体の分子内蛍光消光 Intramolecular Fluorescence Quenching in 1-Naphthylalanylglycine Derivative
With the aid of stationary and time-resolved fluorescence spectroscopy, we investigated solvent, viscosity and temperature effects on the rate of the intramolecular fluorescence quenching process in 1-naphthylalanylglycine derivative having 1-naphthyl(electron acceptor) and diethylamino(electron donor) groups. By comparing with kinetic and thermodynamic parameters for the fluorescence quenching process of the corresponding 1-naphthylalanine derivative, it was shown that in addition to the hydrogen-bonding solvation in the locally excited singlet state of this derivative and the stability of the exciplex intermediate, the average distance between the electron acceptor and donor groups is also a factor in controlling the charge-transfer rate.
