Two new bipyridyl derivatives undergoing the excited state intramolecular proton transfer were synthesized: 5-methyl-<2,2'-bipyridine>-3,3'-diol and 5,5'-dimethyl-<2,2'-bipyridine>-3,3'-diol.Both reveal a strong phototautomeric, largely Stokes-shifted fluorescence and can be used as proton transfer laser dyes.Tuning ranges and lasing efficiences are also reported.
