Structural Origin of the Deformation Propensity of Zeolitic Imidazolate Framework Glasses

Chemistry of Materials, Journal Year: 2024, Volume and Issue: 36(12), P. 6167 - 6179

Published: June 3, 2024

Zeolitic imidazolate framework (ZIF) glasses featuring nanoscale porosity have attracted significant attention due to their potential applications in catalysis, energy storage, gas sorption, and separation. However, mechanical properties may limit some of these applications. In this work, we investigate the structural origins variation zinc-based ZIF-62 (ZnIm2–xbImx) with different benzimidazolate (bIm) (Im) ratios. This is achieved using large-scale molecular dynamics simulations a recent machine learning force field. We find that simulated ZIF glass structures match those determined X-ray total scattering. The relatively large bIm group found hinder reconstruction coordination network during quenching melts, leading more disordered Zn tetrahedra. Both Young's modulus fracture toughness decrease an increase content. Upon fracturing, all organic linkers remain intact, while Zn–N bond switching dissipates strain energy. By correlating atomic static structure, deformation propensity correlated mobility, which turn by initial volume before across variety compositions values. These findings could be helpful for designing fracture-resistant metal–organic future.
