Synthesis, crystal structure and optical property of three coordination polymer constructed from m-phenylenediacrylate acid

• Three new complexes of m-phenylenedicarboxylic acid were synthesized.
• Three metal−organic frameworks exhibiting 1D, 2D, 3D structures, respectively.
• [1] and [2] exhibits a very high quenching effect with acetone.
• [1] and [2] are a potential luminescent sensory material for Zn2+, Ni2+ ions.
• Two logic gates have been constructed using compound [1].

Three new complexes of the wholly deprotonated flexible ligand m-phenylenediacrylate acid (H2mpda), namely, [Zn (mpda) (H2O)] [1], [Pr2(mpda)2(H2O)2(CHOO)2] [2], and [Mn2(mpda)2 (H2O)4] [3], were synthesized by the solvothermal reaction. The complexes were characterized by IR spectroscopy, thermogravimetric analysis, and X-ray single-crystal diffraction. A mixed sample [Nd(mpda)(H2O)(CHOO)·Pr(mpda)(H2O)(CHOO)] [2"] was also synthesized and studied. Compounds [1] and [2] exhibit a selective sensing function with respect to acetone, and they are a potential luminescent sensory material for the selective detection of Zn2+ and Ni2+ ions, respectively. Furthermore, the fluorescent changes of compound [1] upon the addition of cations (Fe3+ and Zn2+, Bi2+ and Zn2+) are utilized to construct two logic gates at the molecular level.
