An Emerging Liquid-Crystalline Conducting Polymer Thermoelectrics: Opportunities and Challenges
Poly(2,5-bis(3-alkylthiophen-2-yl)thieno[3,2-b]thiophene) (PBTTT) synthesis and main strategies to enhance its thermoelectric performance (including doping, composite engineering and aggregation state controlling) are comprehensively reviewed.The thermoelectric performances of PBTTT-related materials are systematically summarized and compared.Future opportunities of PBTTT thermoelectric performance enhancement and effective utilization of its unique melt processibility in multiscale regulation, Credit: Zhenqiang Ye, Mingdong Zhang, Junyang Deng, Lirong Liang, Chunyu Du, Guangming Chen*.

As wearable electronics and IoT sensors proliferate, the demand for flexible, melt-processable thermoelectric (TE) materials that convert body heat into electricity is soaring. Now, researchers from Shenzhen University, led by Prof. Guangming Chen, comprehensively review the latest leaps in poly(2,5-bis(3-alkylthiophen-2-yl)thieno[3,2-b]thiophene) (PBTTT)—a liquid-crystalline conjugated polymer whose figure of merit has catapulted from <0.1 to a record 1.28 at 368 K through asymmetric doping, multi-heterojunction architectures and phonon-blocking strategies.
