Key knowledge gaps persist in explaining how solvation dynamics trigger antisolvent crystallization and oiling-out, how reaction kinetics govern the structural evolution of metal- and covalent-organic frameworks (MOFs and COFs) under dynamic conditions, and how particle breakage can be modeled efficiently for process design. Here, molecular dynamics simulations, microkinetic modeling, and population balance modeling are used to investigate crystallization phenomena across molecular, mesoscale, and continuum scales. We observed that antisolvent crystallization and oiling-out are governed by disruption of hydration shells and solvent reorganization; that local structural evolution in bimetallic MOFs can be resolved through extended X-ray absorption fine structure (EXAFS); and nucleation and growth of MOF thin films can be resolved with in situ grazing incidence wide-angle X-ray scattering (GIWAXS) coupled with mechanistic modeling; and that continuum-scale crystal size distribution and breakage behavior can be predicted using extent-based and analytical population balance formulations.
