Abstract

A cyclotriveratrylene-based molecular cage that favors the formation of a room temperature isolable hemicarceplex with C(70), in the presence of C(60), has been developed. Significant differences in the association and dissociation kinetics of the molecular cage and buckyballs allowed the isolation of C(70) in high purity (≥99.0%) from a commercial fullerene extract without the need for recrystallization or HPLC.

摘要

一种基于环三轮烯的分子笼，在 C(60) 的存在下，有利于形成室温下可分离的半笼 C(70)包合物，已被开发出来。分子笼和富勒烯的缔合和解离动力学的显著差异，使得可以从商业富勒烯提取物中以高纯度（≥99.0%）分离 C(70)，而无需重结晶或 HPLC。
