Correlative Imaging Captures a Fusion Mechanism as the Origin of Single Crystals with Multidomain Appearance

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 4, July 2026.
Nonclassical crystal growth via particle attachment and fusion yields metal–organic framework crystals with multidomain morphologies while retaining single crystallinity. Amorphous particles attach at crystal edges, crystallize, and align with the lattice, driving anisotropic growth, curved surfaces, and cavities.
