A Luminescent Metal-Organic Framework with Lewis Basic Pyridyl Sites for the Sensing of Metal Ions

摘要

The last two decades have witnessed significant progress in the design and synthesis of a new type of porous materials generally referred to as metal-organic frameworks (MOFs) and/or coordination polymers which can be readily self-assembled by the coordination of metal cations/clusters with organic linkers. Extensive efforts on such species have not only led to the creation of a huge number of MOFs of diverse topologies and aesthetic beauty, but also initiated a rational design strategy to construct porous materials with high surface areas, predictable structures, and tunable pore sizes to target some important applications, such as gas storage, separation, catalysis, magnetism, sensing, and imaging. Such progress within this field allows us to rationally design and synthesize porous MOFs with functional sites for specific host-guest recognition and thus to tune their functional properties.
