Conjugated microporous polymers bearing metallophthalocyanine moieties with enhanced visible-light photocatalytic activity

A series of metallophthalocyanine-based conjugated microporous polymers (MPc-CMPs, M = Co, Cu, Zn) were synthesized and used for the photodegradation of organic pollutants for the first time. The as-obtained MPc-CMPs were characterized by UV-vis spectroscopy, Fourier transform infrared spectra (FTIR), scanning electron microscope (SEM). Their photocatalytic activities were assessed by the photodegradation of RhB in the presence of H 2 O 2 under visible light irradiation. Moreover, the possible mechanism to predict this reaction pattern was proposed. As a result, the as-obtained MPc-CMPs, especially CoPc-CMP, exhibit excellent photocatalytic efficiency, recyclability and stability. These results indicate that the MPc-CMPs are potentially applicable in the environmental purification of organic pollutants in the industrial wastewater.
