1 Introduction Organic semiconductors (OSCs) are a versatile class of materials for applications ranging from light-emitting diodes [1] and solar cells [2, 3] to thermoelectric [4, 5], transistors [6, 7], and bioelectronic devices [8, 9]. Their unique combination of mechanical flexibility, solution processability, chemical tunability, and compatibility with low-temperature processing makes them valuable alternatives to traditional inorganic semiconductors [10-13].
