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。5,10,15,20-四(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。
As the center of photochemical reactions in nature, porphyrins and their derivatives have gradually become the focus of research. Based on the characteristics of these compounds, multi-scale, multi-morphological and optical properties of aggregates can be obtained. 5,10,15,20-Tetrakis (p-sulfophenyl) -porphyrin (TPPS) Under certain conditions, environmental perturbations can form chiral aggregates. TPPS and its aggregates can react with ionic block Copolymers formed by the electrostatic interaction of the composite aggregate, such aggregates have the characteristics of a fixed chiral adjustable, size controllable, stable and dispersed forms of sol and so on. This review summarizes the origin of the concept of chiral aggregates and the representative work in this field. At the same time, the work of our group focuses on the preparation and properties of the electrostatic complex TPPS / polycationic chiral aggregates and proposes the field The development trend and work outlook.
