摘要

Cobalt tetraphenylporphyrin (CoTPP) was bond on the side chains of poly(N-vinylimidazole) (PVI) and immobilized on PVI/SiO_2 via axial coordination reactions, respectively, leading to the soluble metalloporphyrin-functionalized PVI (denoted as CoTPP-PVI) and the particles CoTPP-PVI/SiO_2. The above two target products were characterized using spectroscopy methods such as infrared spectrum, electronic absorption spectrum, and fluorescence emission spectrum. And the effects of various factors on the bonding reaction and immobilization reaction of CoTPP were studied in detail. The experimental results show that CoTPP-PVI and CoTPP-PVI/SiO_2 can be prepared favorably through axial coordination reaction of CoTPP with the side imidazole groups of PVI and PVI/SiO_2. In addition, the soluble CoTPP-PVI has all the spectral characteristics of CoTPP. As compared to CoTPP, the adsorption spectra of CoTPP-PVI exhibit red shift obviously. In the immobilization process of CoTPP on PVI/SiO_2, the higher the concentrations of CoTPP and the reaction temperature, the greater the immobilization amount of CoTPP is.
