Enhancement of electrical conductivity due to structural distortion from linear to nonlinear dicarboxylato-bridged Zn(II) 1D-coordination polymers
Abstract
Coordination polymers are useful materials in different fields ofapplications, including the development of supramolecular electricaldevices for the use of renewable energy sources. In this work, we havedesigned two new classes of mixed-ligand one-dimensional coordinationpolymers (1D CPs) [Zn(ADC)(PBT)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>]<sub><i>n</i></sub> (<b>1</b>) and [Zn(Succ)(PBT)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>]<sub><i>n</i></sub> (<b>2</b>) (ADC<sup>2–</sup>, acetylenedicarboxylato; Succ<sup>2–</sup>,succinato; PBT, 2-pyridin-4-ylbenzothiazole) and characterized them byelemental analysis, infrared spectra (IR), single-crystal X-raydiffraction data, powder X-ray diffraction (PXRD), and thermogravimetricanalysis (TGA) data. In the structural motif Zn(II) is bridged by analiphatic dicarboxylato ligand (ADC/Succ) and two axial positions areoccupied by pyridyl-<i>N</i> of PBT along with water coordination. ADC acts as a monodentate carboxylato-<i>O</i> ligand in compound <b>1</b>, whereas in <b>2</b> Succ serves as a carboxylato-<i>O</i>,<i>O</i> chelator. Compounds <b>1</b> and <b>2</b> are both isostructural and construct 3D supramolecular networks by hydrogen bonds (bonding) and <i>π···π</i> interactions along with weak C–H···π interactions. Fascinatingly, compound <b>1</b> exhibits an ∼700 times higher Schottky barrier diode (SBD) electrical conductivity (1.31 × 10<sup>–2</sup> S m<sup>–1</sup>) in comparison to compound <b>2</b> (1.80 × 10<sup>–5</sup> S m<sup>–1</sup>). The impedance electrical conductivities of <b>1</b> (1.22 × 10<sup>–4</sup> S m<sup>–1</sup>) and <b>2</b> (3.24 × 10<sup>–6</sup> S m<sup>–1</sup>) differ significantly; in addition, the direct current conductivities are 1.08 × 10<sup>–4</sup> S m<sup>–1</sup> (<b>1</b>) and 5.55 × 10<sup>–6</sup> S m<sup>–1</sup> (<b>2</b>).To shed light on the charge transport mechanism of the compounds, themobility, transit time, and density of states at a quasi-Fermi levelhave been evaluated. Linear dicarboxylato bridging with an sp-hybridacetylene motif may be the reason for faster charge flow in <b>1</b> in comparison to the sp<sup>3</sup> hybrid nonlinear succinato bridging compound <b>2</b>
