027, τs = 733 ps). The triplet state of the Sn(IV) complexes was investigated by transient absorption spectroscopy. It became clear that the triplet lifetime of the Sn(IV) porphycene (τT = 49.9 μs) was longer when compared to those of the Sn(IV) porphyrin (τT = 32.6 μs) and hemiporphycene complexes (τT = 28.3 μs). These porphyrin isomer Sn(IV) complexes showed the high singlet oxygen generating ability
