将苯基卟啉(PP)功能化的聚甲基丙烯酸缩水甘油酯(PGMA)即PP-PGMA和羟基苯基卟啉(HPP)功能化的PGMA(HPP-PGMA)分别与锌离子发生络合反应,制得高分子化的苯基锌卟啉ZnPP-PGMA或羟苯基锌卟啉ZnHPP-PGMA。采用1H-NMR对ZnPP-PGMA和ZnHPP-PGMA的化学结构进行了表征,用紫外-可见光谱法、荧光光谱法研究了其光谱性能。将ZnPP-PGMA或ZnHPP-PGMA与特丁津作用,研究特丁津对其光谱性能的影响。研究结果表明:高分子化的金属卟啉ZnPP-PGMA和ZnHPP-PGMA都具有强的光谱性能,相对于PP-PGMA和HPP-PGMA,其电子吸收光谱Soret吸收带红移,荧光发射峰蓝移。ZnPP-PGMA和ZnHPP-PGMA分别与特丁津作用后,ZnPP-PGMA的紫外光谱发生一定程度的红移,且ZnPP-PGMA和ZnHPP-PGMA发生明显的荧光猝灭现象。随着特丁津浓度的增大,ZnHPP-PGMA发生荧光猝灭的程度增大。
Phenyl-porphyrin (PP) functionalized poly (glycidyl methacrylate) (PGMA), ie PP-PGMA, and hydroxyphenylporphyrin (HPP) functionalized PGMA (HPP-PGMA) were complexed with zinc ions , To obtain a polymerized phenyl zinc porphyrin ZnPP-PGMA or hydroxyphenyl zinc porphyrin ZnHPP-PGMA. The chemical structures of ZnPP-PGMA and ZnHPP-PGMA were characterized by1H-NMR. The spectroscopic properties were studied by UV-Vis spectroscopy and fluorescence spectroscopy. ZnPP-PGMA or ZnHPP-PGMA and terbutaline were used to study the effect of terbuthyrin on its spectral properties. The results show that both metalloporphyrins ZnPP-PGMA and ZnHPP-PGMA have strong spectral properties. Compared with PP-PGMA and HPP-PGMA, the absorption bands of Soret are red-shifted and blue-shifted . After ZnPP-PGMA and ZnHPP-PGMA reacted with terbuthyrin respectively, the UV spectrum of ZnPP-PGMA was redshifted to a certain degree, and fluorescence quenching of ZnPP-PGMA and ZnHPP-PGMA was observed. As the concentration of terbutaline increases, the degree of fluorescence quenching of ZnHPP-PGMA increases.
