    摘要:Nanoscale curvature-dependent interactions are of
    paramount importance in biological systems. Here, we report
    that nanoscale curvature plays an important role in regulating
    the chirality of self-assembled nanocomposites from chiral
    organic molecules and achiral nanoparticles. Specifically, we
    show that the supramolecular chirality of the nanocomposites
    markedly depends on the nanoparticle curvature, where
    small-sized nanoparticles of high curvature and large-sized
    nanoparticles of low curvature lead to nanocomposites with
    opposite chirality. Quantitative kinetic experiments and
    molecular dynamics simulations reveal that nanoparticle
    curvature plays a key role in promoting the pre-nucleation
    oligomerization of chiral molecules, which consequently
    regulates the supramolecular chirality of the nanocomposites.
    We anticipate that this study will aid in rational design of an
    artificial cooperative system giving rise to emergent assembling phenomena that can be surprisingly rich and often
    cannot be understood by studying the conventional noncooperative systems.
