Thermoelectric properties of metal-(Z)-1,2-dihydroselenoethene-1,2-dithiol coordination polymers

Bulk organic thermoelectric materials namely Cu-dsedt and Cu(I)-dsedt containing (Z)-1,2-dihydroselenoethene-1,2-dithiol (dsedt) linking bridge were synthesized. Elemental analysis, X-ray absorption Spectroscopy (XAS) and X-ray photoelectron spectroscopy (XPS) techniques were used to characterize the polymers. Both of the two metal coordination polymers show p-type electrical transport properties. The highest power factor (PF) and figure of merit (ZT) for Cu-dsedt were 16.4 μV m−1 K−2 and 0.025 at 380 K and the highest PF and ZT for Cu(I)-dsedt reached 13.6 μV m−1 K−2 and 0.013 at 360 K.
