摘 要：Chiral nanoporous nanoarchitectures exhibit potential applications in various fields including chiral separation,sensing and ***-dimensional(2D)supramolecular chemistry offers novel methods to build chiral nanoporous networks from achiral ***,we report a series of chiral nanoporous networks built by an achiral precursor molecule via a stepwise annealing strategy on Ag(100).The nanoporous network morphologies and structural details are characterized by high-resolution scanning tunneling microscopy(STM).It is revealed that all vertices within networks are *** chiral vertices are either dimeric,trimeric,or *** connection of these chiral vertices gives rise to diverse chiral nanopores with varying shapes and sizes.A strict chirality correlation between nanopores and their vertices is ***,enantiomeric vertices of one-pair nanopore enantiomers are always in identical type but opposite *** work serves as a model to investigate the influence of vertex chirality on nanopore chirality of a supramolecular *** attained chiral nanopores could potentially be utilized as templates for surface reaction,chiral recognition,*** mirror-symmetric silver adatoms clusters dictated by chiral nanopore are discerned.
