摘要
Conductive metal-organic frameworks (c-MOFs) have drawn increasing attention for their outstanding performance in energy-related applications. However, the majority of reported c-MOFs are based on 2D structures. Synthetic strategies for 3D c-MOFs are under-explored, leaving unrealized functionality in both their structures and properties. Herein we report Zn-HAB, a 3D c-MOF comprised of hexaaminobenzene and Zn(II). Zn-HAB is shown to have microporosity with a band gap of approximately 1.68 eV, resulting in a moderate conductivity of 0.86 mS cm-1 and a high Seebeck coefficient of 200 μV K-1 at 300 K. The power factor of 3.44 nW m-1 K-2 constitutes the first report of the thermoelectric properties of an intrinsically conductive 3D MOF.
