Abstract
In this study, a novel 1D porphyrin-based polymer, polyphenylporphyrin benzobisoxazole, namely P(PPor-BBO), was synthesized via polycondensation between 5, 15-bis(4-carboxyphenyl)-10, 20-diphenylporphyrin and 4,6-diaminoresor-cinol dihydrochloride. The P(PPor-BBO) is a 1D fully-conjugated heterocyclic aromatic polymer with co-linear and co-planar rigid backbone. Extended fully π-conjugated systems not only enhance chemical stability and lead to insolubility, but also improve photocatalytic active units and light-harvesting capability in the visible-light region. As a result, P(PPor-BBO) shows excellent photocatalytic performance for rhodamine B degradation (150 min, 98%) under visible-light irradiation. It also exhibits easy recyclability and sustainability, indicating it could be as environmentally-friendly catalyst for organic dye wastewater treatment.
