Fluorescence lifetime measurements of purified 7-azaindole in methanol and butanol as a function of temperature are performed. The results indicate that in alcohols there exists a population of 'I-azaindole that is solvated in such a way that excitedstate tautomerixation is no longer a viable mode o

## Abstract The interplay between excited‐state charge and proton transfer reactions in protic solvents is investigated in a series of 7‐azaindole (7AI) derivatives: 3‐cyano‐7‐azaindole (3CNAI), 5‐cyano‐7‐azaindole (5CNAI), 3,5‐dicyano‐7‐azaindole (3,5CNAI) and dicyanoethenyl‐7‐azaindole (DiCNAI).
