We report on a structurally expansion of aerogel materials from traditional main group element-to-element interaction systems, such as oxides, carbons, and chalcogenide clusters, to metal-ligand coordination based systems. By replacing oxygen atoms with organic ligands and replacing silicon atoms with metals (or metal clusters) in conventional aerogels, we produce a new class of metal-organic aerogels (MOAs). These MOAs have unique hierarchical architectures classified from atomic- (primary) to micro- (secondary) to macro- (tertiary) length scales. This work could provide a new perspective on utilizing the growing knowledge base in coordination chemistry, including the concepts of secondary building units in metal-organic frameworks and hard-soft acid-base theory, to facilitate the design and fabrication of aerogel materials for a wide range of scientific and technological applications.
