Copper porphyrin-based conjugated microporous polymers as photosensitizers for singlet oxygen generation

A copper porphyrin-based conjugated microporous polymer (CuPs-CMP@72 h, SBET = 1240 m2 g−1) was synthesized, characterized, and further applied as a promising photocatalyst in the oxidation reaction of 1,3-diphenyllisobenzofuran to 1, 2-phenylene-bis(phenylmethanone). Furthermore, the effect of metal atom and porosity of the CMP network play an important role on generating the singlet oxygen.
