Thermoelectric (TE) materials are receiving increasing attention due to their ability to directly converting heat to electricity. Polymer-based TE materials are particularly fascinating to wearable and mobile devices due to their low density, good flexibility, and low toxicity. The design of a conjugated polymer backbone influences the charge transport and doping efficiency; however, the construction of the polymer backbone for maximized thermoelectric performance is still unclear. Herein, a novel synthesis of a donor-acceptor (D-A) conjugated polymer with an extended planar backbone, C6-ICPDPP, is reported for the investigation of the thermoelectric behavior. The C6-ICPDPP films are formed from two types of solvents with different boiling points, both of which are doped with FeCl3, showing good thermoelectric properties.
