Our work [9-13] has centered on the dye molecule shown in Figure 1. This molecule is officially called 8-hydroxypyrene 1,3,6-trisulfonate and colloquially known as pyranine or HPTS. We also denote it by ROH. Dissolved as its trisodium salt, it is already triply charged in its ground state, where the pK value of the OH group is around 8. In the first excited singlet state the hydroxy group becomes highly acidic [5], with a pK value of 1.4. [Pg.317]
