利用準分子牢籠自富勒烯萃取物中分離純化C60

Abstract

我們合成了一個可與C60形成室溫下可被分離之活門囚籠錯合物(hemicarceplex)之分子牢籠。利用此一分子，我們可以自市售之富勒烯萃取物(fullerene extract)中直接分離純化出純度≥98%之C60，毋須經過液相層析或再結晶的程序。

A cyclotriveratrylene-based molecular cage that favors the formation of a room temperature isolable C60-incarcerated hemicarceplex had been synthesized. Significant differences in the association and dissociation kinetics of the molecular cage and fullerenes allowed the isolation of C60 in high purity (≥98.0%) from a commercial fullerene extract without the need for recrystallization or HPLC.
