Abstract Achieving compact and ordered charge transfer channels is essential for high‐performance non‐fused ring electron acceptors (NFREAs). Herein, this demonstrated that how the stacking arrangement of molecules with macrocycle encapsulated can be regulated via π‐extension, thus resulting in nearly planar molecular backbones, more dual transport characteristics. In RTT‐TT‐4F , these pronounced aggregation features endow its blend film appropriate phase separation, thereby reducing recombination, balancing carrier mobilities, significantly lowering energy loss OSCs. Consequently, ‐based OSCs achieve remarkable power conversion efficiencies 14.45% 19.76% binary ternary devices, respectively. Our findings provide insights into development NFREAs OSC applications.
