Giant Enhancement of Carrier Mobility in Bimetallic Coordination Polymers.

ABSTRACT: Electrically conductive metal-organic coordination polymers (CPs) are promising candidates for a variety of technological applications. However, poor energetic and spatial overlap between the sp-electrons of organic ligands and the d-electrons of metal ion often blocks an effective charge transport (mobility) across CPs. Herein, we present a bimetallic design principle for enhancing carrier mobility in CPs. Bimetallic CPs of Fe(III) and Cr(III) ions coordinated to 1,3,5-benzenetricarboxylic acid (BTC) ligand (Fe-BTC-Cr) exhibited remarkably high carrier mobility at the matching mole ratio (1:1) with enhancement factors of 10² and 10⁴ in comparison to those of monometallic parents, Fe-BTC and Cr-BTC, respectively. The observation was substantiated by lowe
