摘要
通过电化学方法合成了一种具有良好水溶性并能在水及空气中长期稳定存在的C60衍生物, 经电泳实验证实该衍生物带负电荷. 红外光谱及近红外光谱显示该水溶物有稳定键合的C O 和 OH 基, 所以表现出强亲水性. 在可见区(从420 nm 到700 nm )有非常宽的发光谱带, 这是由于Jahn-Teller效应以及C60和 OH 基之间的相互作用引起的.
A new C 60 derivative was synthesized by means of electrochemistry, which exhibits greater water solubility and remains stable in water and air. And very broad white light spectrum from this derivative has been observed. The bright white light emission of the new material results from a perturbation to the normal C 60 molecule due to the Jahn Teller distortion of symmetry structure and the interaction between C 60 and —OH . And negative charges related to electrolysis product have been proved by using of electrophoresis. According to the infrared and Near infrared spectrum the derivative contains hydroxyl groups. And XPS spectrum, 13 C NMR spectrum prove the derivative contains ester carbons.
