Abstract
A picosecond absorption study on the
intermolecular proton transfer of photoexcited
8-hydroxy-1,3,6-pyrene trisulfonate (HPTS)
is presented. The time of formation of deprotonated
excited HPTS was measured for various
solvents. The dependence of this time of
formation on the methanol fraction in watermethanol
mixtures is discussed in terms of a
simple cluster model. Proton transfer rates
were determined in different micellar systems
yielding information on the character of the
micellar surrounding of the proton donator.
