In recent years, our group has focused on the development of high-mobility n-type organic semiconductors based on 3,4,9,10-benzo[de]isoquinolino[1,8-gh]quinolinetetracarboxylic diimide (BQQDI). We previously reported PhC2–BQQDI and its asymmetric analogue PhC2–BQQDI–C5, where a flexible pentyl chain mimics the phenethyl conformation in the crystal—a behavior we termed "molecular mimicry." In this study, we synthesized a symmetrically alkylated C5–BQQDI and investigated how minor doping with PhC2–BQQDI induces structural transformation and enhances electron mobility. In this presentation, we discuss the impact of doping-triggered molecular mimicry on crystal packing and charge transport properties in solution-processed single-crystal transistors.
