Chiral layered coordination polymers have attracted considerable attention not only because of their intriguing physicochemical properties but also ability to exfoliate into chiral nanosheets. metal phosphonates with structures are particular interest due relatively high thermal and water stabilities, corresponding nanosheets rarely reported on. Herein, we report on a pair enantiopure zinc the formula S- R-Zn8(cyampH)8Cl8 (S-Zn, R-Zn), where R-cyampH2 represent R-(1-cyclohexylamino)methylphosphonic acids. They in which {ZnO3Cl} tetrahedra connected by {PO3C} via corner-sharing. By doping analogous chromophore ligands R-(1-naphthalenethylamino)methylphosphonic acid (S-, R-nempH2), obtained compounds R-Zn8(cyampH)8-n(nempH)nCl8 R-Zn-x%, x = 2, 4, 6), exhibited obvious circular dichroism (CD) circularly polarized luminescence (CPL) properties. The bulk samples S-Zn S-Zn-4% were further subjected exfoliation acetone, resulting one–three-layer thicknesses.
