[70]富勒烯衍生物的区域纯度对提高有机光伏发电效率具有重要意义。我们发现，在[70]PCBM中引入支化结构提高了α-异构体的产率。从理论上研究了空间基团对反应机理的影响，揭示了不同反应途径的活化能的差异。
Regio-purity in [70]fullerene derivatives is of great importance to improve the power conversion efficiencies of organic photovoltaics. We found that the introduction of a branched structure to [70]PCBM enhanced the yield of α-isomers. The effect of the steric group in the reaction mechanism was theoretically investigated and a difference in the activation energies within specific pathways was revealed.
