Kinetics of photoinduced electron transfer reactions of ruthenium(II) complexes and phenols, tyrosine, N-acetyl-tyrosine and tryptophan in aqueous solutions measured with modulated fluorescence spectroscopy
文摘
Rapid ET-rates at pH > pKa of the phenols, pH < pKa ETPT-rates are relative slow. pH-dependent functions of the kqobs(s) for PhOH, AcTyrOH oxidations are provided. Steric effect and hydrophobic interaction influence quenching processes.
