Variation of Triplet State Properties of N-mTEG(60)Fulleropyrrolidine Bis-Adducts as a Function of the Bond Path Between the Addends

For a group of seven isomeric N-mTEG[60]fulleropyrrolidine bis-adducts (mTEG = CH2CH2OCH2CH2OCH2CH2OCH3), the quantum yields of singlet oxygen (O2, 11g) production and the maximum triplet molar absorption coef cients were found to be separately correlated with the shortest distances and with the number of bonds connecting the two addends on the fullerene sphere
