Digital Discovery of Synthesizable Metal−Organic Frameworks via Molecular Dynamics‑Informed, High‑Fidelity Deep Learning

Metal–organic frameworks (MOFs) are celebrated for their chemical and structural versatility, and in‑silico screening has significantly accelerated their discovery; yet most hypothetical MOFs (hMOFs) never reach the bench because their synthetic feasibility remains unknown. Herein, a deep‑learning proxy based on the Tabular Prior‐Data Fitted Network (TabPFN) is introduced that predicts free energy with high fidelity. The fine‐tuned surrogate attains a coefficient of determination ( R 2 ) of 0.96 and a mean absolute error (MAE) of 0.67 on the hold‑out test set, preserves strong temporal generalization ( R 2 = 0.89 and MAE = 1.35), as well as robust extrapolation on a chemically diverse blind set. Applying the surrogate to a well‐established hMOF library, we rapidly flag prime hMOF candidates that fall within the synthetic‑likelihood window observed for experimentally realized MOFs. This study delivers a practical bridge between digital reticular design and laboratory synthesis, transforming synthetic‑likelihood assessment from a computational bottleneck into a routine, high‑throughput step. Beyond MOFs, the approach provides a general framework for accelerating free‑energy‑driven materials discovery with minimal loss of accuracy, opening a new avenue to data‑driven exploration of complex chemical spaces.
