Organic semiconductors can be designed and constructed in π‐stacked structures instead of the conventional π‐conjugated structures. Through‐space interaction (TSI) occurs in π‐stacked optoelectronic materials. Thus, unlike electronic coupling along the conjugated chain, the functional groups can sta...
