Abstract

Significance The translation of crystalline porous materials from molecular-level design to practical technologies requires control beyond framework structures. Although crystalline porous materials offer precisely defined pores and functional sites， their practical performance is strongly influenced by particle-scale factors， including morphology， pore accessibility， shaping processes， and interfacial structures. Crystalline porous particles serve as a bridge between structural design and engineering applications， enabling their integration into adsorptive separation， catalysis， membrane processes， electrochemical devices， sensing systems， and biomedical applications.

Progress This review discusses recent advances in crystalline porous particles from structural design to engineering implementation. Representative crystalline porous systems， including zeolites/molecular sieves， metal-organic frameworks （MOFs）， covalent organic frameworks （COFs）， hydrogen-bonded organic frameworks （HOFs）， and composite porous materials， are summarized with emphasis on the relationship between crystal structures， particle architectures， and functional properties. Zeolites and molecular sieves remain important platforms for shape-selective catalysis and adsorptive separation owing to their robust inorganic frameworks， uniform micropores， and tunable acidic properties. MOFs and COFs have expanded the structural diversity of crystalline porous materials through controllable coordination and covalent chemistry， enabling regulation of pore environments， framework dynamics， electronic structures， and particle morphologies. Supramolecular crystalline porous materials further demonstrate the role of reversible intermolecular interactions in constructing molecular cavities and adaptive pore systems. Composite crystalline porous materials integrate multiple components and interfaces to couple molecular recognition， transport properties， and processability.

Conclusions and Prospects Crystalline porous particles are evolving from structure-oriented materials toward application-oriented systems with controlled architectures across multiple length scales. Future progress requires establishing quantitative relationships among crystal structures， defects， particle morphology， hierarchical porosity， and macroscopic performance. Understanding structural evolution under realistic operating conditions， including humidity， impurities， pressure variation， reactive environments， and long-term cycling， remains essential. Integration of scalable synthesis， standardized engineering evaluation， operando characterization， and experiment-calibrated multiscale modeling will be critical for designing crystalline porous particles with predictable performance in practical applications. Molecular-level adsorption and diffusion parameters should be translated into effective particle properties before being incorporated into reactor models， and breakthrough and cyclic experiments should be used to validate and refine model predictions.
