    • Light irradiation of phenanthroline ligands in air-equilibrated dichloromethane solution leads to absorption spectral changes similar to those observed upon protonation, which are also reversible upon addition of base. However, the extensive absorption and emission changes of 8 and 9 in strongly acid environment have been detected also upon removal of oxygen from the solution and working in a dark room. Accordingly we can exclude that the peculiar luminescence behaviour of 8 and 9 in acidic dichloromethane is related to extensive photochemical degradation
