Polymers <b>1</b>–<b>10</b> are isostructural and feature a 1D chain based on binuclear units in which Ln<sup>3+</sup> polyhedra are interconnected by bridging Hpqc ligands and terminal nitrates. The infinite chains are further extended to a three-dimensional supramolecular framework through π···π stacking and hydrogen bonding interactions. This series affords an opportunity to study the lanthanide contraction effect, demonstrating that the sum of Ln–O distances proportional to this contraction follow a quadratic decay as a function of the number <i>n</i> of f electrons. The photoluminescence spectra show that these complexes are highly sensitized by Hpqc and exhibit characteristic Ln<sup>3+</sup> (Sm (<b>1</b>), Eu (<b>2</b>), Tb (<b>4</b>), Er (<b>7</b>), and Yb (<b>9</b>)) and ligand centered (Dy (<b>5</b>), Ho (<b>6</b>), Tm (<b>8</b>), and Lu (<b>10</b>)) luminescence in both visible and near-infrared (NIR) regions. The magnetic properties of <b>4</b>–<b>7</b> have also been investigated. 2013-12-04 00:00:00 photoluminescence spectra show 1 D chain NIR Ho terminal nitrates lanthanide contraction effect Eu Er supramolecular framework f electrons Lanthanide Coordination Polymers Magnetic Properties Sm crystal Structure Lu lanthanide coordination polymers Ln Tm Tb Yb Dy solvothermal reaction Multiplex Photoluminescence Quinoline Carboxylate LigandA series Hpqc ligands number n
