高效液相色谱法纯化内源性金属富勒烯耗时长,成本高。因此,许多快速和廉价的非色谱方法已被开发用于金属富勒烯的大规模纯化。本文综述了近年来金属富勒烯非色谱纯化方法的研究进展。路易斯酸络合是分离金属富勒烯和空富勒烯最有效、最有效的方法之一。金属富勒烯的第一氧化电位是影响Lewis酸基分离效率的关键因素。超分子方法是分离不同大小和形状的富勒烯和金属富勒烯的有效方法。化学/电化学还原和外面体功能化也被用于大规模分离和纯化金属富勒烯。
The purification of endohedral metallofullerenes by high performance liquid chromatography is very time-consuming and expensive. A number of rapid and inexpensive non-chromatographic methods have thus been developed for large-scale purification of metallofullerenes. In this review, we summarize recent advances in non-chromatographic purification methods of metallofullerenes. Lewis acid-based complexation is one of the most efficient and powerful methods for separation of metallofullerenes from empty fullerenes. The first oxidation potential of metallofullerenes is a critical factor that affects the separation efficiency of the Lewis acid-based method. Supramolecular methods are effective for separation of fullerenes and metallofullerenes that are different in size and shape. Chemical/electrochemical reduction and exohedral functionalization are also utilized to separate and purify metallofullerenes on a large scale.
