摘要

The hydrofullerene C _(50)H _(10) is synthesized by low-pressure benzene-oxygen diffusion combustion. The structure of C _(50)H _(10) is identified through NMR, mass spectrometry, and IR and Raman spectroscopy as a D _(5h) symmetric closed-cage molecule with five pairs of fused pentagons stabilized by ten hydrogen atoms. UV/Vis and fluorescence spectrometric analyses disclose its optical properties as comparable with those of its chloride cousin (C _(50)Cl _(10)). Cyclic and square-wave voltammograms reveal that the first reduction potential of C _(50)H _(10) is more negative than that of C _(50)Cl _(10) as well as C _(60), with implications for the utilization of C _(50)H _(10) as a promising electron acceptor for photovoltaic applications.
