Abstract |
Thermoelectric materials have received considerable attention for sustainable energy harvesting system from sun and waste heat energy. Among the materials, conducting polymers (CPs) are good candidate and showed advantages over inorganic thermoelectric materials due to their controllable optoelectronic properties, flexibility, and easy processability. Compared to p-type, n-type polymers have been poorly explored mainly due to the difficulty in synthesis and lack of design principles. Herein we report synthesis of diketopyrrolopyrrole (DPP) based polymer in that various monomer structures were introduced to tune orbital energies and ultimately thermoelectric properties. Due to the high electron mobility, low LUMO level, and the electron withdrawing nature of the DPP based π-conjugated polymers, they showed n-type thermoelectric properties. Preparation, calculated orbital energies, and thermoelectric characterization of DPP based polymers will be presented.
