摘要：

The photophysical properties of a series of porphyrin diacids have been studied theoretically at the density functional theory level and experimentally by measuring decay kinetics of S-1 and T-1 excited states of the diacids. The existence of a new pathway of the effective non-radiative deactivation of the lowest singlet and triplet excited states of the porphyrin diacids due to electron transfer from the acid residues to the porphyrins has been suggested.
