研究了叠氮乙酰胺与C60 反应 ,其反应机理为经过一个三唑啉中间体结构形成最终产物 ;分析表征了C60氮乙酰胺 ,通过量化计算确定了氮丙啶闭环结构为热力学稳定结构 ;应用倍频Nd :YAG脉冲激光测试了它的光限幅性能 ,确定其光限幅机制为反饱和吸收 ,长波长 (70 7nm)激光的限幅效果要优于C60 ,表明C60 衍生物是一种非常有希望的激光限幅材料。
The reaction mechanism of azidoacetamide with C60 was studied. The reaction mechanism was that a triazoline intermediate structure was formed to form the final product. The C60 azeotrope was analyzed and characterized, and the closed-loop structure of aziridine was determined to be a thermodynamically stable structure by quantitative calculation. The pulsed Nd:YAG laser has been tested for its optical limiting performance and its optical limiting mechanism has been proved to be anti-saturation absorption. The limiting effect of the long wavelength (70 7nm) laser is better than that of C60, indicating that the C60 derivative is a Very promising laser limiting material.
