Morphological Anisotropy in Metal–Organic Framework Micro/Nanostructures

Abstract Anisotropy plays a unique role in the structural regulation of metal–organic frameworks (MOFs) and their composites, especially at the micro‐ and nanoscale. However, there is a lack of a understanding of MOF micro/nanoparticles (MNPs) from the perspective of morphological anisotropy. In this Minireview, recent advances in anisotropic MOF MNPs are summarized, with a focus on how morphological anisotropy leads to innovative structures and modulates properties. First, anisotropic pristine MOF MNPs with diverse morphologies are introduced and classified by their morphology‐dependent and morphology‐independent anisotropy. Secondly, the anisotropy‐enabled site‐selective higher‐order construction of MOF‐based materials is highlighted. Finally, challenges and prospects for anisotropic MOFs are discussed, aiming to provide inspiration for further developments in this interesting research field.
