Organic semiconductors offer tunable properties through molecular design using organic synthesis. DMADT exists in anti- and syn-isomers with distinct transport characteristics in previous study. X-ray and physicochemical measurements cannot identify the factors of the different charge transport characteristics. This study, we apply operando electron spin resonance (ESR) method to DMADT-based organic transistors to probe charge behavior at microscopic level and clarify isomer-dependent transport mechanisms.
