A new class of high‐performance n‐type organic thermoelectric materials , self‐doping perylene diimide derivatives with modified side chains, is reported. These materials achieve the highest n ‐type thermoelectric performance of solution‐processed organic materials reported to date, with power factors as high as 1.4 μW/mK 2 . These results demonstrate that molecular design is a promising strategy for enhancing organic thermoelectric performance.
