摘要

A novel reactive rnetallophthalocyanine derivative, zinc tetra(2,4-dichloro-1,3,5-triazine)arninophthalo-cyanine (Zn-TDTAPc), was prepared and immobilized on poly(N-isopropylacrylarnide) (PNIPAArn) by covalent bonding to obtain a therrnosensitive polymer (Zn-TDTAPc-g-PNIPAAm). Compared with zinc tetraaminophthalocyanine (Zn-TAPc), Zn-TDTAPc-g-PNIPAArn exhibits excellent solubility in water and in most organic solvents. Furthermore, it has a special therrnosensitive property in water and the lower critical solution temperature (LCST) is 34.1℃. It was found that both dissolved and precipitated Zn-TDTAPc-g-PNIPAArn present high photoactivity evidenced by the experiment of photocatalytic degra-dation of 1, 3-diphenylisobenzofuran (DPBF) in the presence of Zn-TDTAPc-g-PNIPAArn. These proper-ties suggest that it can be used potentially in photodynarnic therapy (PDT).
