Excitation of Pt[Me-AHP] was performed at 355 nm due to the comparably low absorption at 532 nm. The changes in absorption upon excitation were found to be rather small (Figure ), indicating much less efficient population of the triplet state. As expected, the observed changes were consistent with the shape of the ground-state absorption spectrum. The Finally, we investigated the behaviour of Mn[Me-AHP] in the same conditions. No ground state bleaching or appearance of new absorption was detected upon excitation of deoxygenated solutions of the complex in 9:1 v/v ethanol/tetrahydrofuran or toluene (Figure ).
