摘要：

Structural and electronic properties of group-2 metal-containing endohedral metallofullerenes (Ca/Sr/ Ba@C-80, Ca/Sr/Ba@C-82, Ca/Sr/Ba@C-84) are investigated for the first time by UV-Vis-NIR absorption spectroscopy and high-resolution C-13 NMR. Direct evidence of the endohedral nature and cage structures are revealed by these measurements. Furthermore, we have found that each metallofullerene has 2-4 structural isomers, which have been isolated by multistage high-performance liquid chromatography. These isomers have different cage structures and give characteristic UV-Vis-NIR absorption spectra.
