Synthesis, structure and luminescent property of a pillared-layer coordination polymer [Pb(BPDC)] (BPDC = 4,4′-biphenyldicarboxylate)
چکیده انگلیسی

A new 3D pillared framework has been obtained through self-assembly of 4,4′-biphenyldicarboxylic acid (4,4′-H2BPDC) and Pb(NO3)2 under solvothermal reaction and characterized by TGA, IR spectroscopy, element analyses, and X-ray single crystal diffraction. The X-ray structure analysis reveals that the oxygen atoms of the carboxylate groups link the Pb(II) to form metal-carboxylate layers, and 4,4′-BPDC ligands act as pillars to connect adjacent layers into a novel 3D pillared framework, where the BPDC displayed a rare μ6 coordination mode of each BPDC linking with six Pb(II) ions. Furthermore, the highly thermally stable compound 1 exhibits blue photoluminescence at room temperature in the solid state.

Graphical AbstractA novel metal-organic polymer 1, [Pb(BPDC)] possesses parallel 2D infinite Pb-carboxylate layers bridged by carboxylate oxygen atoms. The 2D layers are further linked by the rigid 4,4′-BPDC ligands into a 3D pillared framework.Figure optionsDownload as PowerPoint slide
