    All-Fullerene Electron Donor-Acceptor Conjugates

  • Original language description

    The synthesis and characterization of a covalent all-fullerene C-60-Lu3N@I-h-C-80 electron donor-acceptor conjugate has been realized by sequential 1,3-dipolar cycloaddition reactions of azomethine ylides on Lu3N@I-h-C-80 and C-60. To the best of our knowledge, this is the first time that two fullerenes behaving as both electron donor (Lu3N@I-h-C-80) and acceptor (C-60) are forming an electroactive dumbbell. DFT calculations reveal up to 16 diastereomeric pairs, that is, 8 with syn and 8 with anti orientation, with the anti-RSSS isomer being the most stable. Spectroelectrochemical absorption and femtosecond transient absorption experiments support the notion that a C-60(.-)-Lu3N@I-h-C-80(.+) charge-separated state is formed. Spin conversion from the charge-separated singlet state C-60(.-)-Lu3N@I-h-C-80(.+) into the corresponding triplet state is facilitated by the heavy-atom effect stemming from the Lu3N-cluster, which, in turn, slows down the charge recombination by one order of magnitude.
