To date, high-performance organic electrochemical transistors (OECTs) are all based on polythiophene systems. Donor-acceptor (D-A) conjugated polymers are expected to be promising materials for OECTs owing to their high mobility and comparatively low crystallinity (good for ion diffusion). However, the OECT performance of D-A polymers lags far behind that of the polythiophenes. Here we synergistically engineered the backbone, side chain of a series of diketopyrrolopyrrole (DPP)-based D-A polymers and found that redox potential, molecular weight, solution processability, and film microstructures are essential to their performance. Among the polymers, P(bgDPP-MeOT2) exhibited a figure-of-merit (μC*) of 225 F cm<sup>–1</sup> V<sup>–1</sup> s<sup>–1</sup>, <a>over one order of magnitude higher than previously reported D-A polymers. Besides, the DPP polymers exhibited high hole mobility over 2 cm<sup>2</sup> V</a><sup>−1</sup> s<sup>−1</sup>, significantly higher than all D-A polymers employed in OECTs, leading to fast response OECTs with a record low turn-off response time of 30 μs. <a>The polymer also exhibited better stability than polythiophene systems with current retention of 98.8% over 700 electrochemical switching cycles.</a> This work provides a systematic solution to unleash the high-performance and fast-response nature of D-A polymers in OECTs.

Abstract Organic thermoelectric (OTE) materials have been regarded as a potential candidate to harvest waste heat from complex, low temperature surfaces of objects and convert it into electricity. Recently, n-type conjugated polymers as organic thermoelectric materials have aroused intensive research in order to improve their performance to match up with their p-type counterpart. In this review, we discuss aspects that affect the performance of n-type OTEs, and further focus on the effect of planarity of backbone on doping efficiency and eventually the TE performance. We then summarize strategies such as implementing rigid n-type polymer backbone or modifying conventional polymer building blocks for more planar conformation. In the outlook part, we conclude forementioned devotions and point out new possibility that may promote the future development of this field.
