英文摘要	reactions of 2,5-bn2c70 (bn = ch2ph) with hydroxide and arcn (ar = ph, m-clph) followed by quenching with i-2 and bnbr afforded dibenzylated and tetrabenzylated oxazolino[70]fullerenes, respectively. the latter has a novel structural configuration, in which the addends are positioned from the polar to the transequatorial region. a key structural feature of this compound is that the oxygen atom of the oxazoline ring is bound to the equatorial belt region of c-70, giving structural change in its reduced state. this enables stabilization of the reduced state, suppressing charge recombination dynamics in organic solar cells to give a high open-circuit voltage (0.85, 0.93, and 1.11 v in devices using p3ht, ptb7, and dpp(tbfu)(2), respectively).
