Preventing Benzoquinone-Based Catalyst Aggregation Enables the One-Step Synthesis of Highly Conductive Poly(benzodifurandione) without Post-Reaction Purification.

ABSTRACT: Conductive polymers have become crucial in advancing various electronic applications. While p-type materials like poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) are widely used and produced at scale, the development of high-performance n-type polymers has lagged due to challenges in synthesis and scalability. In this work, a novel method is introduced to synthesize the highly conductive n-type polymer poly(benzodifurandione) (PBFDO) using α-tocopherylquinone (α-TQ) as a catalyst. This approach eliminates the need for post-reaction dialysis, a major obstacle to large-scale PBFDO production. By preventing catalyst aggregation, high electrical conductivity (>1320 S cm^-1) is achieved, which remains stable in air for over 180 d, significantly simplifying the proce
