Synthesis of Star Poly(N-isopropylacrylamide) with Two Zinc-porphyrins as Core and End-groups Respectively via ATRP & “CLICK” Chemistry and Photocatalytic Performance Study

Abstract

Through the cooperation of atom transfer radical polymerization (ATRP) and click reaction, the star-shaped poly(N-isopropylacrylamide) with 5,10,15,20-tetra(4-(2-bromoisobutoxy)phenyl)-21H, 23H-zincporphyrin (ZnTHPP-4Br) as the core and 5-(4-propargyloxyphenyl)-10,15,20-triphenylzinc-21H, 23H-porphyrin (ZnTPP-Py) as the end groups (ZnTHPP-(PNIPAM-ZnTPP)4) was prepared, and it was used as photocatalyst for the degradation of Rhodamine B under visible-light irradiation. The structure of star-shaped polymer was characterized by FT-NIR, 1H NMR, UV-Vis and GPC clearly. The photocatalytic property study indicated that the ZnTHPP-(PNIPAM-ZnTPP)4 had higher photocatalytic activity than before click reaction and can be recycled by warming.
