Synthesis, Characterization and Photocatalytic Properties of Metal Phthalocyanine Modified Thermoresponsive Polymers

In this study, 3-hydroxyethoxyphenyl-9(10), 16(17), 23 (24)-decyloxy-zinc phthalocyanine (HDPcZn) was first prepared by liquid phase catalysis, and then it esterified with Poly-(N-isopropylacrylamide) which have two carboxyl groups (TRIT-PNIPAM) at the end to obtain a linear thermoresponsive polymer (PcZn-PNIPAM-PcZn) phthalocyanines end. The characterized FT-IR, 1 H NMR, EDS UV-vis, photocatalytic performance of tested 1,5-dihydroxynaphthalene (DHN) as model pollutant. results showed that PcZn-PNIPAM-PcZn exhibited excellent oxidation ability for DHN under visible light irradiation (2h, 78.1 %).
