摘要

摘要采用原位电子还原光谱(EPR)研究了在不同溶剂混合物中，以TiO2或三乙胺为供电子底物，单-和双- n -甲基富勒吡啶盐光诱导形成富勒烯阴离子自由基。相对介电常数和氢键给予能力等溶剂性质影响了光还原产率和阴离子自由基的稳定性。

Photoinduced Electron Transfer to Fulleropyrrolidinium Salts Studied by EPR

Abstract The photoinduced formation of fullerene anion radicals from mono- and bis-N-methylfulleropyrrolidinium salts in the presence of TiO2 or triethylamine as electron donating substrates was investigated using in situ EPR spectroscopy in various solvent mixtures. The photoreduction yield and stability of anion radicals generated are affected by the solvent properties, such as relative permittivity and hydrogen bond donation ability.
