Side‐Chain Branching Dictates the σ–S Coupling in Conjugated Polymer Thermoelectrics

Advanced Electronic Materials, EarlyView.
The correlation between conductivity and Seebeck coefficient has been extensively studied in numerous works. Nevertheless, its association with side chains has not been thoroughly explored. In this work, we found that the distance between the branching points of side chains and the molecular backbones has a significant effect on thermoelectric ...
