Monte Carlo simulation of electric conductivity for pure and doping fullerene (C60)

In this paper, we have used Monte Carlo (MC) method to simulate and study the temperature and doping effects on the electric conductivity of fullerene (C60). The results show that the band gap has reduced by the doping and the charge carrier transport is facilitated from valence band to conduction band by the temperature where is touched a 300 K. In this case, the conductivity reached a value of $4\times {10}^{-7}\text{S}{\text{cm}}^{-1}$. The electric conductivity of C60 can increase by the triphenylmethane dye crystal violet (CV) alkali metal to reach $4\times {10}^{-3}\text{S}{\text{cm}}^{-1}$ at 303 K. Our results of MC simulation have a good agreement with those extracted from literature [10], [33].     

Solvent-free Synthesis of Dihydrofuran-fused [60]Fullerene Derivatives by High-speed Vibration Milling

Solvent-free organic reactions have been attracting great interest of chemists due to the elimination of the usage of harmful organic solvents,low costs,and simplicity in the procedure1.Solvent-free mechanochemical reactions of fullerenes were explored and are significant for the reactions of fullerenes because the low solubility of fullerenes in common organic solvents requires large quantity of organic solvents and some novel fullerene reactions could only occur in the solid-state reaction2.…

激光解吸电离质谱法分析富勒烯

论述了用激光解吸电离谱法分析富勒烯。因在电离过程中富勒分子不发生裂解，因此这种方法可直接用于富勒烯混合物的分析而勿需任何预分离。还给出了用本法分析较大、较稳定富勒烯分子的质谱图。

本实验采用金属有机化学方法成功地将富勒烯分子引入到ＰＮＶＣ侧链形成ＣＢＰ（ＣｈａｒｍＢｒａｃｅｌｅｔＰｏｌｙｍｅｒ）型共聚功能材料，研究了其ＵＶ－ＶＩｓ谱行为。结果表明，Ｃ_（６０）或Ｃ_（６０）／Ｃ_（７０）混合物化学修饰的产物其紫外可见谱明显向长波方向移动，谱峰范围由２８０ｎｍ扩展至８７０ｎｍ。Ｃ_（６０）含量增加，红移程度增大，在可见区域的吸收程度亦增加。产物主要存在５个特征峰，分别位于２１５ｎｍ、２６５ｎｍ、２９８ｎｍ、３３５ｎｍ、３４５ｎｍ处，其中２１５ｎｍ峰为Ｃ_（６０）仅存的特征峰。最后讨论了不同合成条件与产物硝化处理对其ＵＶ－ＶＩＳ谱行为的影响。     

Self-inclusion properties of C60-linked calix[5]arene

C₆₀-linked calix[5]arenes were synthesized and their intramolecular binding properties were investigated. The self-inclusion ratio of the C₆₀ moiety was determined by using UV-vis spectroscopy, and the ratio depends on chain length, temperature, and solvent. Influence of temperature and solvent was explained by the thermodynamic data of the intramolecular complex formation process.
