Regioselective electrochemical hydroalkylations of [60]fullerene-fused furochromenone with alky halides in the presence of TFA or AcOH unexpectedly afford three types of tetra-functionalized [60]fullerene derivatives in high yields. The usage of AcOH and TFA predominantly gives 1,2,3,4-adducts with the five-membered heterocycle retained at [6,6]-junction and 1,2,3,16-adducts with the five-membered heterocycle rearranged to [5,6]-junction, respectively. The obtained 1,2,3,16-adducts can be transformed into 1,2,3,4-adducts by treatment of NaH followed by AcOH.

Open-cage C₆₀ derivatives were prepared containing a OH or NH₂ on each of the two phenyl rings above the rim of the orifice. These amino and hydroxyl groups on the phenyl ring showed similar reactivity as aniline and phenol, thus acting as a useful handle for attaching other functional groups and also for making polymers containing open-cage fragments.

Reaction of [60]fullerene with cheap and readily available β-substituted ethylamines in the absence or presence of arylacetaldehydes under the assistance of Cu(OAc)₂ afforded a series of unreported fullerodihydropyridine-3-ones as a new family of fullerene derivatives, which may have promising applications in photovoltaic devices due to the existence of a large π-conjugated system on the dihydropyridine-3-one ring.

An unprecedented Pd-catalyzed migration reaction of [60]fullerene with allyloxy-tethered aryl iodides is presented for the preparation of rare [60]fullerene-fused allylbenzofurans. The reaction features high chemo- and regio-selectivity. This transformation proceeds via a sequential C—O bond cleavage/allyl-migration/intermolecular cycloaddition cascade process.

A heteronuclear di-metallofullerene, ScY@C_3v(8)-C₈₂, which contains a mixed rare-earth metal-metal bond, was successfully synthesized and characterized. The combined experimental and theoretical results confirm that both Sc and Y atoms transfer two electrons to the C_3v(8)-C₈₂ cage. In particular, a covalent Sc-Y σ² bond, which has never been reported before, is proven to be formed inside C_3v(8)-C₈₂ fullerene cage.

The role of metal species on cluster configuration has been elucidated through a comparative study of Lu₂O@C_s(6)-C₈₂ and Er₂O@C_s(6)-C₈₂.

Novel amino acid decorated water-soluble fullerene derivatives with pronounced anti-influenza activity have been synthesized.

We investigated the important role of C₆₀Br₈ in the stereoselective synthesis of fullerene bis-adducts using the reaction of C₆₀Br₈ with alkoxyaniline, and surprisingly prepared a sequence of nontethered trans-4 bis(aziridino)[60]fullerene with superior stereoselectivity. To the best of our knowledge, the controllable synthesis of non-tethered bis(aziridino)[60]fullerene with high stereoselectivity has never been reported.

This review presents the strategies for synthesis and application of functionalized fullerenes including endohedral metallofullerenes as electron transport layers, additives and interfacial modifiers for improving the performance and stability of PSCs.

A one-pot efficient protocol has been developed to construct diversified 1,4–fulleroazaindole frameworks from simple and readily available azaindoles, bromoalkanes, and triphenylamines.
