The new chiral metal-organic coordinationpolymer [ZnLH·4 H2O]n+/[HL]n− (H2L is 2-(l-prolylamino)benzene-1,4-dicarboxylic acid) was synthesized based on the available l-proline-substituted 2-aminobenzene-1,4-dicarboxylic acid derivative. The unique crystalstructure of the new compound was established by powder X-ray diffraction.

Self‐Assembly of Helical Nanofibrous Chiral Covalent Organic Frameworks
Two chiral COFs with well-defined, one-handed double-helical nanofibrous morphologies are constructed for the first time involving a chiral aminal linkage. By adjusting the amount of acetic acid during synthesis, the helicity of the resulting COF double helices can be readily inversed. Circularly polarized luminescence of the COF double helices is achieved via transferring chirality to achiral fluorophores
