Abstract

The benzylporphyrin (PP)-functionalized polyglyceryl methacrylate (PGMA) and the hydroxylbenzylporphyrin (HPP)-functionalized PGMA

i.e.

PP-PGMA and HPP-PGMA

were coordinated with Zn

ion respectively

resulting in the Zn porphyrin-functionalized PGMA

i.e.

ZnPP-PGMA and ZnHPP-PGMA. The chemical structures of ZnPP-PGMA and ZnHPP-PGMA were characterized by nuclear magnetic resonance (

H-NMR) spectroscopy. The spectroscopic properties of ZnPP-PGMA and ZnHPP-PGMA were studied by means of UV-Vis spectroscopy and fluorescence spectroscopy. The axial coordination reaction between two kinds of Zn porphyrin-functionalized PGMA and terbuthylazines was studied by using the fluorescence spectrum titration method. The affective factors for fluorescence character of axial coordination reaction were investigated. The results show that both ZnPP-PGMA and ZnHPP-PGMA have possessed strong spectral characteristics. Comparing with PP-PGMA and HPP-PGMA

the Soret absorption bands of ZnPP-PGMA and ZnHPP-PGMA exhibited obvious red shift

and the blue shift occurred for Q emission bands of them. In addition

both the Soret and Q absorption bands of ZnPP-PGMA exhibited red shift in the electronic absorption spectra. The fluorescence quenching occurred in the product of terbuthylazine. The fluorescence quenching for ZnHPP-PGMA was a little less than ZnPP-PGMA. It is because the hydrogen bonding between ZnHPP-PGMA and terbuthylazine led to the weaker axial coordination. Moreover

the fluorescence quenching of ZnHPP-PGMA was strengthed with the increasing concentration of terbuthylazine.
