摘要

作为自然界中光化学反应的中心

卟啉及其衍生物逐渐成为研究的焦点。基于该类化合物的特性可获得多尺度、多形态且光学性质各异的聚集体。5

20-四(对磺酸基苯基)-卟啉(TPPS)在一定条件下受环境的微扰可以形成手性聚集体

TPPS及其聚集体可与离子型嵌段共聚物通过静电作用形成的复合聚集体

此类聚集体具有手性特征固定可调、尺寸可控、溶胶形式稳定分散等特征。本文综述了手性聚集体这一概念的由来以及该领域的代表性工作

同时结合本课题组工作着重对静电复合型TPPS/聚阳离子手性聚集体的制备及性质进行讨论

并提出该领域的发展趋势及工作展望。

Abstract

As the center of the natural photochemical reaction

porphyrin and its derivates have attracts more attention from the scientists. Aggregates of porphyrin with different optical properties can be obtained from nanometer to micron with various morphologies. 5

20-tetrakis-(4-sulfonatophenyl)-porphyrin (TPPS) can form chiral aggregates under some small perturbations. Cationic block copolymer can form complex aggregates with TPPS or its aggregates through electrostatic interactions. These aggregates have stable and tunable chirality and disperse as colloidal solution with a controllable size. This article reviewed the origin of the chiral aggregate and the latest developments in this field. We mainly discuss the preparation and character of the cationic block copolymer/TPPS complex aggregate based on our published work. Finally

some possible approaches in this field are proposed and the prospective on the future development is tentatively discussed.
