Growth and characterizations of two-dimensional metal-organic frameworks

Metal-Organic Frameworks (MOFs) are a class of porous materials with a crystalline structure that can be designed based on extremely tunable building blocks of organic molecules and metal ions. They are typically insulators but making them [pi]-conjugated with two-dimensional structure results in high electrical conductivity. This makes the two-dimensional a-conjugated MOFs (2D [pi]MOFs) good candidates for applications that need porous conductors such as supercapacitors and batteries. More importantly, tunability of the crystal structure enables us to explore exotic physical properties, including topological protection. This great potential has inspired the synthesis of various 2D [pi]MOFs, but their crystal growth remains challenging, preventing the characterization of intrinsic electrical properties. In this thesis, I will explain the growth mechanisms of 2D [pi]MOFs and the limitations of conventional growth methods.
