摘要

用敏感于微环境变化的紫外-可见吸收光谱和荧光光谱

研究了系列双亲卟啉(对四羟基苯基卟啉P0及其烷氧基衍生物P1

P2)在四氢呋喃和SDS胶束体系中的定位性质和聚集行为

考察了不同微环境下

卟啉分子中不同侧链取代基对紫外-可见吸收光谱和荧光光谱的影响.研究结果表明

系列双亲卟啉在THF溶液中以单体形式存在

其侧链取代基不影响卟啉的电子态;在SDS胶束溶液中

紫外-可见吸收光谱随着双亲卟啉侧链取代基的增加

吸光度减小

半峰宽增加

荧光光谱发生了荧光猝灭

表明系列双亲卟啉中侧链取代基不同

其聚集状态不同

从而导致不同的增溶位置变化.

Abstract

Three sorts of amphiphilic porphyrins(4-hydroxyphenyl porphyrins P0 and its alkoxy derivates P1

P2)were solublized in THF solutions and SDS micellar solutions.The position-made and aggregation behavi or were studied by means of UV-VIS and fluorescence spectra influenced by diffe rent side-chain substituents in varieties of microenvironments.The results ind icates that amphiphilic porphyrins exists as monomers in THF solutions

and the effects of the side-chain substituents on the electronic states of porphyrins a re negligible.The UV-VIS spectra's absorbance decreases

FWHH increases

fluo rescence quenching occurs in fluorescence spectra as amphiphilic porphyrin's si de-chain substituents increase.It demonstrates that amphiphilic porphyrin's s ide-chain substituents vary

its aggregations vary

leading to varied solubiliz ation position.
