主 题:supramolecular polymer symmetry-breaking chirality assembly vortex
摘 要:The generation of chirality in supramolecular structures from achiral building blocks has remained a challenge for a long *** this study,we present a vortex-assisted chiral supramolecular polymerization from a series of achiral C3-symmetric monomers,where the mechanism of symmetry-breaking is systematically *** increasing the supersaturation,at the early stage of nucleation and growth,highly ordered assemblies can be generated as the initial chiral ***,chiral assemblies from high supersaturation are hard to interwind into clusters,where clusters as nuclei are not conducive to being fractured by sheer force of vortex ***,it is concluded that chiral assemblies in the nucleation stage possess low energy barrier,so that chiral nuclei could be fractured and replicated by the *** enlarging the initial chiral bias,the major chiral nuclei can evolute into the final chiral polymers.
