Properties of nitride clusterfullerenes
Spectroscopic characterizations of fullerenes are another focus of our group in the fullerene research besides the efforts of synthesizing novel carbon nanostructures. The spectroscopic methods implemented by our group include UV-Vis-NIR, mass spectroscopic, FTIR, Raman, NMR, XPS, high-energy photoemission spectroscopy etc., providing valuable information of the molecular, electronic, and vibrational structures of fullerenes. For instance, the electronic property and band-gap of nitride clusterfullerenes are comprehensively investigated by UV-Vis-NIR spectroscopy and the strong influence of the cage isomeric structure and cage size on electronic structure of nitride clusterfullerenes are elaborately demonstrated. High-energy spectroscopic studies could give the effective valency of the metal atom of the nitride cluster. In specific, our group expertises in the study of vibrational structure of fullerenes, which is important for the characterization of the endohedral fullerenes in general since it is sensitively correlated to the isomeric structure of the cages. Besides, the structure of the encaged cluster could be probed by its vibrational pattern given by both infrared and Raman spectroscopy. The vibrational structures of many C80-based clusterfullerene M3N@C80 (I, II) (M=Sc, Gd, Dy, Tm) have been comprehensively studied by our group aiming to getting detailed insights to their isomeric structures. Our group also extends this study to some new clusterfullerenes based on other cages such as M3N@C78 (M=Sc, Dy, Tm) and Sc3N@C68 (see figure).
