A new 2D homochiral zinc coordination polymer (Zn-CP) with 52-member rings was synthesized by solvothermal method. X-ray single crystal diffraction results show that the initial ligand (H 2 ibga = (4-(1 H-imidazol-1-yl)benzyl)-L-glutamic acid) cyclized and crystallized in monoclinic with space group P 2 after coordination with zinc(II) ions. Phase purity and thermal stability of Zn-CP were verified by X-ray powder diffraction (PXRD) and thermogravimetric (TG), respectively. Additionally, Zn-CP can recognize tetracycline (TC), Fe 3+ and ascorbic acid (AA) rapidly and selectively in aqueous solution, with low detection limits (LODs) of 3.49 nM, 4.42 nM and 0.38 µM, respectively. The detection mechanisms have been investigated in detail. Graphical Abstract
