Abstract: Chiral supramolecules have great potential for use in chiral recognition, sensing, and catalysis.Particularly, chiral supramolecular biocoordination polymers \(SBCPs) provide a versatile platform for characterizing biorelated processes such as chirality transcription.Here, we selectively synthesize homochiral and heterochiral SBCPs, composed of a naphthalene diimide ligands and Zn ions, from enantiomeric and mixed R-and S-ligands, respectively.Notably, we nd that the chiral self-sorted SBCPs exhibit multifunctional properties including photochromic, photoluminescent, photoconductive, and chemiresistive characteristics, thus can be used for various sensors.Speci cally, these materials can be used for detecting a hazardous amine materials due to the electron transfer from hydrazine to the SBCP surface and for enentioselectively sensing the chiral species naproxen due to the different binding energies with regard to their chirality.These results provide guidelines for the synthesis of chiral SBCPs and demonstrate their versatility and feasibility for use in various sensors covering photoactive, chemiresistive, and chiral sensors.Procedure **Synthesis of the homochiral H2AlaNDI ligands** 1. Re ux 1,4,5,8-naphthalenetetracarboxylic dianhydride \(1.34 g; 0.005 mol) and L-or D-alanine \(0.89 g; 0.01 mol) in pyridine \(600 mL) for 12 h.2. Add aq HCl \(300 mL water and 100 mL concd HCl), as the volume of the mixture was reduced to 10 mL.
