A Chiral Metal-Organic Frameworks: Evolution of Morphology and Crystallization on Surface

A chiral Metal-organic frameworks (MOFs) are obtained from a pyridine-based tetrahedral ligands. The resulting MOFs show a homogeneous hexagonal morphology, the size of which can be tuned by changing the concentration of ligands and metal salts. Time-dependent experiments reveal the crystallization process go through a kinetic phase, which dissolve into solution as crystallization goes on. The chiral MOFs can grow on pyridine-modified silicon surface with orientation. Microstructure analyzes show there are defects between the interface and MOFs.
