ISOLATED AND ENCAPSULATED FULLERENE AND SALT

摘要

PROBLEM TO BE SOLVED: To provide isolated M@C60 or M@C70.;SOLUTION: The isolated and encapsulated fullerene is shown by M@C_2n (wherein M is a single or a plurality of metal atoms or an atom group including them; 2n is 60 or 70). The ratio of the peak intensity of other fullerene to that of the encapsulated fullerene is ≤0.5% in laser desorption ionization time-of-flight mass spectra (hereafter called LDI-TOF-MS) of positive modes.;COPYRIGHT: (C)2011,JPO&INPIT
