Two Novel 2D Zn (II) Coordination Polymers with Quinoline-3-Carboxylic Acid and Tetraphenylphthalic Acid: Synthesis and Photoluminescence Properties

Two novel two-dimensional (2D) Zn coordination polymers,namely [Zn(qnl)2]n (Zn-qnl) and [Zn2(tpp)(OH)2(H2O)]n (Zn-tpp) (qnl = quinoline-3-carboxylate anion, tpp = tetraphenyl phthalate anion) have been hydrothermally synthesized and discussed their solid state photoluminescent properties. Two novel Zn coordination polymers with ligands quinoline-3-carboxylic acid (Hqnl) and tetraphenylphthalic acid (H2tpp) have been prepared and characterized by X-ray crystallography. Zn-tpp and Zn-qnl show a 2D hinge layer and a 2D layer with quadrilateral meshes, respectively.
