摘 要: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 ZnCl2,800W微波辐照180 s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。By exposure to microwave irradiation, α-tetra-(p-carboxyphenoxy)phthalocyanine zinc (ZnPc) was syn- thesized and the properties of the product were investigated by 1H-NMR, UV-Vis and FT-IR spectroscopy. The io- dide 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) , 0.4 mL of 1, 8-diazabicyclo [ 5,4,0 ] undec-7-ene ( DBU, as catalyst), 0. 1 g of 3- (4-carboxyphenoxy) phthalonitrile and 0.03 g of ZnCI2 with a microwave power of 800 W for 180 s. 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.
