9-Oxo-9,10-dihydro-acridine-4-carboxylic acid in both methanol and acetonitrile possesses a dual fluorescence and complex fluorescence intensity decay, whereas 9-oxo- 9,10-dihydro-acridine-2-carboxylic acid shows only one emission band and monoexponential fluorescence intensity decay. Theoretical calculations, using a semiempirical PM3 method, confirm, in the case of 9-oxo-9,10-dihydro-acridine-4-carboxylic acid, the excited state intramolecular proton transfer process from nitrogen atom to the oxygen of carbonyl of the carboxylic group.
