Selenium‐Incorporated Polymerized Nonfullerene Acceptors/SWCNT Composites with Polymer‐Assisted n‐Doping for High‐Performance Organic Thermoelectrics

open access: yesAdvanced Functional Materials, EarlyView.
Selenium‐incorporated polymerized nonfullerene acceptor PCB2Se forms a strong supramolecular complex with SWCNTs, enabling a record‐high zT of 0.29. Sequential N‐DMBI doping, mediated through a polymer‐assisted electron‐transfer pathway, successfully converts the PCB2Se/SWCNT composite into an efficient n‐type material with an impressive power factor ...
