A self-assembled porous Zn(II) metal–organic framework based on fluorinated bis-pyridinecarboxamide derivative ligand: Synthesis, structure and properties

Abstract

A zinc metal–organic framework [Zn(tfpbbp)(Ac)2]n (1) has been prepared by reacting N,N′-[(2,3,5,6-tetrafluoro-1,4-phenylene)bis(methylene)]bis(pyridine-4-carboxamide) (tfpbbp) with Zn(Ac)2·2H2O and characterized by single crystal X-ray diffraction and TGA analysis. Single crystal X-ray diffraction analysis indicates that in solid-state (1) is a 1-D zigzag chain, which further self-assembles into a 3-D supramolecular porous structure through hydrogen bonding interactions. The polymer (1) exhibits photoluminescent property at room temperature.
