The extended view on the empty C2(3)-C82 fullerene: isolation, spectroscopic, electrochemical, and spectroelectrochemical characterization and DFT calculations.
[摘要]：An extended study of the spectroscopic and redox properties of the C82 fullerene is presented. Among the nine isolated-pentagon-rule (IPR) isomers of the C82 fullerene the C82(3) isomer with C2 symmetry is the only stable, empty fullerene structure formed in the arc burning process that can be isolated in an isomerically pure form. Here, its formation and isolation are described and its structure is confirmed by exptl. spectroscopic studies as well as time-dependent DFT calcns. The electrochem. of the C82(3) isomer was studied in detail by cyclic voltammetry and spectroelectrochem. The anionic species of C82 with the charge ranging from C82- to C824- were successively generated in o-dichlorobenzene soln. at room temp. and characterized by in situ ESR and visible/near-IR (visible/NIR) spectroscopy. The data give new insights into the charged states of the C82(3) fullerene.
