Cover Story: Using the technique of matrix isolation spectroscopy, we obtained vibrationally resolved phosphorescence spectrum of porphycene, an isomer of porphyrin. This allowed us to determine the triplet state origin. While the S1←S0 transitions have similar energies in both isomers, phosphorescence of porphycene is located at a much lower energy. Such an energy pattern strongly suggests that the orbital origin of T1 corresponds in both isomers to the second excited singlet state. Understanding the nature of the lowest triplet state in porphyrinoids is important because of possible applications of these compounds, e.g., as photosensitizers in photodynamic therapy.
