A thermoelectric copper-iodide composite from the pyrolysis of a well-defined coordination polymer

Abstract

Coordination polymer 1 was prepared from CuI and a flexible [SNS] ligand L in acetonitrile. The thermal decomposition of 1 yielded a CuI-rich thermoelectric carbon composite 2, which is relatively light, thermally stable and robust. Composite 2 possesses high Seebeck coefficients (700–950 μV K⁻¹) from rt to 204 °C after an optimization cycle.
