Gas Storage in Fullerenes

Fullerenes and in particular C₆₀ have been shown to store effectively a wide range of gases from simple monatomic rare gases to diatomics and polyatomics. A review of the research in this area conducted at ANSTO is given. The trapping of Ar, Kr, Xe, and CO₂ are discussed in detail whilst preliminary results pertaining to N₂O, CH₄, CF₄, C₂H₆ and SF₆ are also reported. A range of techniques have been used to elucidate both the structure of the new fullerene intercalated solid and the trapped gas itself. The preponderant techniques used, include infra-red absorption spectroscopy (IR), X-ray powder diffraction a (XRD), neutron powder diffraction (NRD), transmission electron microscopy (TEM), and thermal gravimetric analysis (TGA).     

FTIR和^13C—NMR研究球笼烯钕系聚丁二烯链结构

用ＦＴＩＲ和１３Ｃ－ＮＭＲ法测定了Ｎｄ（ｎａｐｈ）３－Ａｌ（ｉ－Ｂｕ）３－Ｃ６０衍生物催化体系及添加Ｃ６０合成的聚丁二烯的链节含量。结果表明,球笼烯钕系聚丁二烯的顺－１,４链节达９８．８％,反－１,４链节为０．８％;当添加的Ｃ６０用量为Ｃ６０／Ｂｄ＝１．６×１０－４（摩尔比）时,顺－１,４链节降至９３．６％,反－１,４链节升至４．６％,反－１,４链节ＩＲ特征吸收峰较普通钕系聚丁二烯向高频移动了６ｃｍ－１,这表明Ｃ６０分子与Ｂｄ共同参与了向活性中心竞争配位过程。     

The interaction between conjugated polymer and fullerenes

The fluorescence of Poly(2-methoxy,5-(2′-ethylhexloxy)-p-phenylene-vinylene) (MEH–PPV) quenched by fullerenes was examined, and the results indicate that this quenching is not dynamic. Strong interaction in the excited state between them may be caused by the photoinduced charge transfer and π–π conjugated system interaction. More direct and convincing evidence of the charge transfer complex are presented. © 1998 John Wiley & Sons, Inc. J. Appl. Polym. Sci. 70: 599–603, 1998
