Synthesis, characterization, and fluorescence of a highly stable two‐dimensional zinc coordination polymer

Abstract

AbstractIn this work, we have successfully introduced the nitrogen‐rich aromatic ligand 5,5′‐bipyrimidine (BYPM) as auxiliary ligands into the 3‐nitrophthalic acid (NPTA) system, and a Zn(II)‐based coordination polymer [Zn2(BYPM)(NPTA)2]n (1) has been synthesized under solvothermal condition. The 1 is characterized by elemental analysis, Thermogravimetric analysis (TGA), single‐crystal X‐ray diffraction, and X‐ray diffraction patterns (PXRD). The single‐crystal X‐ray analysis indicates that 1 propagates into a layer‐like framework along the ac plane through the coordination Zn2+ ions and further forms a three‐dimensional supramolecular framework through intermolecular C−H⋅⋅⋅O and C−H⋅⋅⋅N hydrogen bonds. Thermogravimetric analysis and powder X‐ray diffraction experiments indicate that 1 has high thermal and solvent stability. Meanwhile, the fluorescence of 1 has been explored.
