Abstract
Nanoscale metal–organic frameworks (nanoMOFs) are promising porous nanomaterials for diverse applications, such as catalysis, imaging, functional membranes, and drug delivery. At the nanoscale, the size of materials is critical for their properties and utility. Herein, a straightforward and convenient strategy is developed for size precisely controlled synthesis of nanoMOFs. Unlike other approaches, this strategy can directly give nanoMOFs of predicable sizes within a wide range without the time consuming trial‐and‐error process and without the addition of additives. In this approach, the preciseness of size control is ensured by the separated and controlled nucleation and growth. The size controlled synthesis of 9 kinds of most widely studied nanoMOFs confirms the versatility of this strategy. More importantly, this approach can be utilized for scale‐up synthesis of nanoMOFs with the same precise size control.
