Guiding metal organic framework (MOF) morphology is a hot topic in recent years. However, the preparation without the need for chemical additives still remains a challenge. For the first time, Liao group reported a unique surface guiding approach in controlling the crystal morphology formation of MOFs on disrupted monolayer-covered substrates. Selective molecule removal generates diverse matrices rich in artificial molecular defects in a monolayer to direct the dynamic crystal growth process. The tail groups of surface residue molecules act as nucleating sites and the exposed molecule chain backbones stabilize a particular facet of MOF nuclei in the dynamic growth. Porous architectures prepared in this approach can also act as templates for ligand-free metal nanocluster synthesis and represent distinct crystal morphology-dependent optical properties. These findings provide a unique thought on MOF crystal morphology guidance, and pave a new route for the accompanied property investigation and application.
