微波法制备α-四(4-羧基苯氧基)酞菁锌及其光催化性能

采用微波辐照法合成了α-四（4-羧基苯氧基）酞菁锌（ZnPc），以UV-Vis，FT-IR等手段对其进行了表征，并以碘量法测定了产物的单线态氧量子产率。结果表明：以2mL N，N二甲基甲酰胺（DMF）为溶剂，0.4mL 1, 8二氮杂二环5, 4, 0]十一碳-7-烯（DBU）为催化剂，0.1g 3-4-羧基苯氧基邻苯二甲腈及0.03g ZnCl 2，800W微波辐照180s后，可得到产率为75.3%的ZnPc，比传统加热合成产率提高了403%。对1, 3二苯基苯并呋喃（DPBF）光漂白实验表明，所合成的ZnPc具有较高的单线态量子产率、光活性和稳定性。

Microwave assisted synthesis of α-tetra-(p-carboxyphenoxy) phthalocyanine zinc and its photocatalytic properties

By exposure to microwave irradiation, α-tetra(p carboxyphenoxy)phthalocyanine zinc (ZnPc) was synthesized and the properties of the product were investigated by 1H NMR, UV Vis and FT IR spectroscopy. The iodide method was used to measure the quantum yields of singlet oxygen formed by the product. ZnPc was prepared in a yield of 75.3% by irradiating a mixture of 2mL of N, N dimethylformamide (DMF, as solvent), 0.4mL of 1, 8 diazabicyclo［5,4,0］undec 7 ene (DBU, as catalyst), 0.1g of 3(4-carboxyphenoxy) phthalonitrile and 0.03g of ZnCl 2 with a microwave power of 800W for 180s. The yield was improved by 40.3% compared with that of the conventional method of synthesis. Chemical quenching tests with 1,3 diphenylisobenzofuran (DPBF) indicated that ZnPc gives high singlet oxygen quantum yields and photo catalytic ability, and good photo stability.
