The rates of proton ejection from 2-naphthol-3,6-disulfonate (pK* = 0.5 ± 0.1) and 8-hydroxy 1,3,6-pyrene trisulfonate (pK* = 0.4 ± 0.1) have been found to be 3.1 × 1010 s-1 and 3.2 × 1010 s-1, respectively. This is in keeping with the scaling of the ejection rate inversely with the excited state pK*.
