　　报告人简介：

　　Min-Hui Li is a Research Director in CNRS serving in ENSCP (Ecole Nationale Supérieure de Chimie de Paris) in Paris. She received her B.Sc. (1986) and M.Sc. (1988) from Tsinghua University in Beijing, and her Ph.D. (1993) in Polymer Chemistry and Physical Chemistry from Pierre & Marie Curie University (now Sorbonne University) in Paris. Her Ph.D. work was performed in the Laboratoire Léon Brillouin, CEA Saclay in France. After a post-doc in the French Institute of Petroleum, she joined the French National Center for Scientific Research (CNRS) as a tenure researcher in 1994. She served in the Centre de Recherche Paul Pascal in Bordeaux from 1994 to 1997, in the Curie Institute (Institut Curie) in Paris from 1997 to 2014. Since 2015, she works in ENSCP (also called Chimie ParisTech). Min-Hui Li’s current research mainly focuses on soft matter chemistry, especially on amphiphilic polymers, liquid crystal polymers and elastomers, photosensitive polymers, and polymer self-assemblies for functional soft materials.

　　简介内容：生命依赖于由平面脂双层膜和膜蛋白组成的薄膜。脂双层起屏障作用，而蛋白质则负责大多数膜功能（如物质交换和运输）。在此，我们介绍了一种两亲性聚合物膜，通过适当的聚合物设计，模拟了脂双层的屏障作用和蛋白质的运输功能。这些膜可以是聚合物囊泡中的泡状膜，或是在聚合物立方体和六边形膜中的立方体和六边形膜。通过在聚合物结构中引入聚集诱导发光（AIE）组分，这些膜具有发光和光响应性。我将讨论具有AIE发光功能的明亮荧光聚合物囊泡、立方体和六边形膜的例子，以及聚合物囊泡中的光驱动穿孔和囊泡-胶束转变。这些系统可能会激发对刺激响应型纳米结构在药物输送和生物成像方面的新研究。
