Photophysical properties of porphycene derivatives (18 π porphyrinoids)

Absorption and fluorescence spectral data and triplet energy content, as well as quantum yields of fluorescence, of triplet state formation, and of sensitized generation of singlet molecular oxygen, O₂(¹∆g), of 38 porphycene derivatives are reported. Long-wavelength absorption and the efficiency of...
