Enhanced Thermoelectric Properties of a Semiconducting Two-Dimensional Metal-Organic Framework via Iodine Loading.

We report the first result of a study in which molecular iodine has been incorporated via incipient wetness impregnation into the two-dimensional semiconducting metal-organic framework (MOF) Cu 3 (2,3,6,7,10,11-hexahydroxytriphenylene) 2 Cu 3 (HHTP) 2 to enhance its thermoelectric properties. A power factor of 0.757 μW m -1 K -2 for this MOF was obtained which demonstrates that this provides an effective route for the preparation of moderate-performance thermoelectric MOFs.
