Metal-Organic Frameworks in Nanotechnology
Metal-organic frameworks (MOFs) are typically synthesized into pure and bulk-sized crystals, and thus their usability is limited by the lack of compatibility with advanced technologies. Strategies to intermingle reticular chemistry and nanotechnology will lead to new forms of functional materials and applications. This talk will show how MOFs and nanotechnology can be combined into special constructs and successfully work together for solar cell and protein separation.
For the solar cell application, nanocrystalline Ti-based metal-organic framework (nTi-MOF) particles (ca. 6 nm) are synthesized and successfully used in perovskite solar cells (PSCs) to result impressive power conversion efficiencies of 18.94% and 17.43% for rigid and flexible devices, respectively. For protein separation, the heterogeneous pores within MOF membrane is shown to have pH-responsive switchable selectivity for the flow-assisted separation of similarly sized proteins
