Organic conjugated polymers (CPs), such as regioregular poly(3-hexylthiophene) (RR-P3HT), are promising for advanced electronics due to their tunable semiconducting properties and efficient charge transport. Molecular orientation significantly impacts performance, influencing charge mobility and efficiency. In this study, RR-P3HT thin films were utilized in reservoir computing (RC) to process signals by mapping inputs into higher-dimensional spaces. Optimizing molecular orientation improved charge transport and reservoir dynamics, enhancing RC performance for tasks like pattern recognition and sequence prediction. Building on previous findings on π-π stacking effects, we investigated how film randomness affects computational accuracy, revealing critical insights for neuromorphic applications.
