双亲性C60衍生物水相聚集行为

富勒烯C₆₀几乎不溶于水中,从而阻碍了对富勒烯的进一步研究和潜在应用。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现状及研究进展进行了详细系统的介绍。本文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。

Aggregation Behavior of Amphiphilic C60 Derivatives in Aqueous Solution

Poor solubility of C₆₀ in water is among the main obstacles which hinder the potential utilization of fullerene-containing materials. Amphiphilic C₆₀derivatives, 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, progress of the study on 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, solvent polarities, concentration, temperature and counter anion.
