With increasing pace, crystalline open frameworks are moving to larger scale, mature applications that stretch as broadly catalysis, separation, water purification, adsorption, sensing, biomineralization and energy storage. A particular challenge in this development can be the unexpected variation material properties from batch batch, even when a cursory analysis would indicate no process changes occurred. Our team has lived journey many projects where pilot scale production of metal-organic for use devices been key milestone suffered difficulties performance departures. In Perspective, we aim share some learning outcomes hope it will further speed field. major materials scale-up is between batches. Here, pilot-scale discussed suggestions provided help improve large-scale synthesis development.

Abstract Metal‐organic frameworks (MOFs), renowned for structural diversity and design flexibility, exhibit potential in catalysis. However, the pursuit of higher catalytic activity through defects often compromises stability, requiring a delicate balance. Traditional trial‐and‐error method optimizing synthesis parameters within complex chemical space is inefficient. Herein, taking typical MOF UiO‐66(Ce) as an illustrative example, closed loop workflow built, which integrates machine learning (ML)‐assissted prediction, multi‐objective optimization (MOO) experimental preparation to synergistically optimize defect content thermal stability efficient hydrogenation dicyclopentadiene (DCPD). An automatic data extraction program ensures accuracy, establishing high‐quality database. ML employed explore intricate synthesis‐structure‐property correlations, enabling precise delineation pure‐phase subspace accurate predictions properties. After two iterations, MOO model identifies optimal protocols high (>40%) (>300°C). The optimized exhibits superior performance DCPD, validating precision reliability our methodology. This ML‐assisted approach offers valuable paradigm solving trade‐off riddle materials field.
