1|INTRODUCTION Chirality spans over almost every size range,from mole-cules to biological systems and even to galaxies.It is one of the fascinating geometrical properties with a lot of amazing manifestations in the material world.As chemi-cal researchers,we are more interested in chirality at the molecular scale and nanoscale.Chiral molecules are found important in life science,agrochemicals,pharma-ceutical industries,biosensing,display materials,and so forth.1–5 Chirality stems from a structure lacking sym-metry elements of inversion symmetry and mirror‐plane,which makes the structure not superimposable with its mirror image.Without these two kinds of symmetries,any structure is chiral,besides conventional chiral organics or spiral inorganic structures.The essence of chirality is the stereochemistry of molecules or nanostructures.
