Abstract

The kinetics of the excited-state processes of the charged fluorescent probe N, N, N-trimethyl- 3-(l-pyreny1)-1-propanaminium perchlorate (PROBE) in tetrahydrofuran are reported. At very low concentrations PROBE decays monoexponentially with a lifetime z of 236 f 1 ns, from which b1= l/z= 4.2 x lo6 sl is obtained. Upon addition of the quaternary ammonium salt N, N, N-trimethyl-l-dodecanaminium perchlorate a biexponential decay function is needed ...
