双亲性C_(60)衍生物水相聚集行为

Aggregation Behavior of Amphiphilic C_(60) Derivatives in Aqueous Solution

富勒烯C60几乎不溶于水,从而阻碍了对富勒烯的进一步研究和应用。双亲性C60衍生物在水相中自组装形成聚集体,在水相具有一定的溶解度,其特殊的结构及性能引起了科学家的广泛关注。本文对双亲性C60衍生物在水相中聚集行为的研究进展进行了系统的介绍。第一部分主要阐述了双亲性C60衍生物的结构,根据修饰到C60表面的功能基类型对双亲性C60衍生物进行了分类。第二部分主要阐述了双亲性C60衍生物在水相的聚集行为以及pH值、溶剂极性、浓度、温度和抗衡离子等因素对聚集行为的影响。

Poor solubility of C60 in water is one of the main obstacles which hinder the potential utilization of fullerene-containing materials. Amphiphilic C60 derivatives, which are relatively soluble in water, self-assemble into aggregates in water, have drawn great attention due to their special structures and properties. In this review, the aggregation behavior of amphiphilic C60 derivatives in aqueous solution is described in detail. In the first part, we describe the structural morphology of the highly soluble amphiphilic C60 derivatives, particularly summarize these C60 derivatives according to the side groups attached to fullerene core. In the second part, we mainly discuss the aggregation of amphiphilic C60 derivatives in aqueous solution and the facts that can regulate the aggregation process, such as pH, solvents polarities, concentration, temperature and counter anion.
