报告摘要：
In this talk, I will present recent work by our group on the use of supramolecular chemistry to address challenges in synthesis, materials science and systems chemistry.
Control over the selectivity of fullerene bis-addition reactions was achieved by encapsulating C60 in a three-shell complex (“Russian Doll”). Thanks to the combined template effects of a self-assembled cage and nanohoop [10]CPP,[1a] the C60 trans-3 bis-adduct was obtained with ideal chemo-, itero- and regioselectivity,[1b] which has recently enabled the synthesis of unprecedented C60/[10]CPP [2]catenanes.
Control over the length of self-assembled nanofibers was achieved by the living supramolecular polymerization of all-cis fluorinated cyclohexanes.[2a] The exceptionally high dipole moment of the C6H6F5OR motif[2b] gave rise to folded monomers that only polymerized into nanofibers of double-helical topology upon addition of seeds.
Control over the persistence of supramolecular assemblies over time was achieved in chemically-fuelled phosphoramidate and acylphosphate systems. Generating chemically-driven steady states from organophosphates is far from trivial, but holds great promise for the creation of chemically-driven molecular machines and transient self-assemblies.
