Cyano‐Functionalized Fused Bithiophene Imide Dimer‐Based n‐Type Polymers for High‐Performance Organic Thermoelectrics

in n-type OTEs, attributed to the optimized polymer electronic properties and film morphology with improved molecular packing and higher crystallinity assisted by solution-shearing technology. The PF value is the record of n-type polymers for OTEs to date. This work demonstrates a facile approach to designing high-performance n-type polymers and fabricating high-quality films for OTE applications.
