Nanorods of a Novel Highly Conductive 2D Metal-Organic Framework Based on Perthiolated Coronene for Thermoelectric Conversion

Abstract

Conducting metal-organic frameworks (MOFs), especially those with high electrical conductivity (>10-3 S cm-1) catch more and more attentions, nowadays. Here, nanorods of a novel metal-organic framework (MOF) based on perthiolated coronene (PTC) is synthesized by a homogeneous reaction. The structure, morphological and component analysis reveal that the nanorods is composed with a 2D Kagomé with the formula of [Ni3(C24S12)]n. The compressed sample of the nanorods display electrical conductivity of ~9 S cm-1 at 300 K and a weak semiconductor-like temperature dependence. Furthermore, moderate Seebeck coefficient of 47.0 µV/K and extremely low thermal conductivity of 0.2 W m-1 K-1 result in a thermoelectric with Figure of Merit (ZT value) of 0.003 at 300 K. This is best p-type TE performance in conducting MOFs ever reported.
