Strategies have been explored for developing strongly fluorescent species out of a weakly fluorescent Schiff base, 2-(((pyridin-2-ylmethyl)imino)methyl)phenol (salampy). The locally excited enolic state of salampy undergoes an intramolecular proton transfer...

Experiments and computations reveal that 1,2-disubstituted anthrol carbaldehydes are not ESIPT reactive, whereas 2,3-disubstituted anthrols undergo efficient barrierless ultrafast ESIPT, where the typical dual emission from locally excited states and tautomers was not observed.
