Abstract: | 1-azacarbazole hydrogen-bonded dimers undergo photoinduced double proton transfer reaction in their lowest excited singlet state. A second emission band with a maximum at 510 nm arises from a tautomer formed in the excited singlet state as a result of the double proton transfer process. |
