Abstract
We present the self-healing of defects and enhanced crystallinity in uniaxially aligned poly(3-hexylthiophene) (P3HT) crystal via molecular doping with F4TCNQ. Using eutectic friction transfer (EFT), highly aligned P3HT films (P3HT_EFT) were fabricated, exhibiting superior alignment and planarity compared to spin-cast P3HT (P3HT_SC). Upon doping, the self-healing of defects in P3HT_EFT films led to a significant increase in the charged-ordered phase, transforming transient amorphous phases into well-ordered crystalline domains. In contrast, the conventional P3HT_SC films formed settled amorphous phases and exhibited no self-healing behavior.
