Area of Science:

• Materials Science
• Computational Chemistry
• Chemical Engineering

Background:

• Metal-organic frameworks (MOFs) are advanced porous materials with diverse applications.
• Understanding the self-assembly mechanisms of MOFs is crucial for designing novel structures with tailored properties.
• Current simulation methods often lack the flexibility to model the wide range of MOF topologies.

Purpose of the Study:

• To investigate the fundamental processes governing the growth of various MOF structure types.
• To validate the simulation toolkit by successfully predicting the self-assembly of known MOF nets.

Main Methods:

• Designed simulation building blocks based on the topology and symmetry of MOF nets.
• Modeled MOF nodes using sphere-union polyhedra with specific bead interactions.
• Simulated linkers with shapes and binding facets reflecting their coordination environment.
• Implemented a modular self-assembly model simulation kit.

Main Results:

• Successfully modeled the self-assembly of 34 distinct MOF nets using the developed toolkit.
• Demonstrated the ability to computationally predict MOF structures based on designed building blocks.
• Validated the toolkit's efficacy in capturing key aspects of MOF self-assembly.

Conclusions:

• The developed coarse-grained simulation toolkit provides a powerful platform for studying MOF self-assembly.
• This approach enables the design and prediction of novel MOF structures.
• The findings contribute to a deeper understanding of MOF formation processes.
