The integration of machine learning into OLED materials design faces significant constraints due to an overemphasis on large datasets and complex models, which often neglect chemical relevance and interpretability. A shift towards prioritizing data quality over quantity, incorporating domain-specific molecular representations and physics-informed descriptors, is proposed. This approach, exemplified by methods like the organic electronic fingerprint (OEFP) and the inclusion of physical priors, aims to improve predictive accuracy while reducing data needs and enabling mechanistic insights for rational molecular design. AI
