A novel polymer membrane ( TPP‐M ) with strong light harvesting ability within the entire visible‐ light spectrum has been prepared, in which the meso‐tetrakis(4‐cyanophenyl) porphyrin ( TPP‐1 ) as a functional unit is highly crosslinked through an aromatic nitrile trimerization reaction. The designed triazine framework controls the size of the π‐conjugation and retains the excellent photophysical properties of monomeric porphyrin, such as strong absorption and high singlet oxygen quantum yield. Due to these excellent photophysical properties and low solubility in common organic solvents, polyporphyrin membranes, as efficient singlet oxygen ( 1 O 2 ) sensitizers, could be easily recycled and reused for the photo‐oxidation of 1,5‐dihydroxynaphthalene (DHN).
