Synthesis of Organic Photodimeric Cage Molecules Based on Cycloaddition via Metal-Ligand Directed Assembly

摘要

Metal—ligand directed assembly has proven successful in the design and synthesis of metal—organic assemblies (e.g., metal-organic frameworks and metal—organic polyhedra), which have emerged as an important class of solid-state materials and have exhibited interesting properties toward their utilization in many applications, from ion exchange to gas storage to separations to catalysis. Recently, we have introduced a method to target rigid and directional single-metal ion based molecular building blocks toward the design and synthesis of metal—organic assemblies (MOAs), including zeolite-like frameworks, a subclass called ZMOFs, that exhibit tunable extra-large cavities which offer potential in (host—guest)— guest sensing.
