A novel 2D bilayer architecture generated via π-π interactions and host–guest molecular recognition: assembly and structure of {[Cd(Htma)(bpy)(H2O)]·(H2tp)0.5·2H2O}npolymer (tma = trimesate, bpy = 4,4′-bipyridine, tp = terephthalate)

Abstract

The interdigitation of the lateral tma ligands from two adjacent 44 nets via aromatic π-π interactions and host–guest molecular recognition gives rise to a novel 2D bilayer supramolecular architecture formed by the {[Cd(Htma)(bpy)(H2O)]·(H2tp)0.5·2H2O}n polymer. An interested parallel/parallel interpenetration of the 44 net appears in this bilayer supramolecular architecture through other 2D H-bonded 44 nets formed by tma molecules that H-bond with water molecules. This compound, obtained from a hydrothermal reaction, crystallizes in the triclinic P-1 space group and exhibits a broad intense fluorescent emission upon photoexcitation at 311 nm.
