Writing in Nature Materials, Paolo Falcaro and co-workers have developed a remarkable approach for the preparation of thin films of highly ordered and aligned MOF crystallites on a silicon substrate. Their strategy is used to trap fluorescent guest molecules, which are then aligned by the MOF thin film. The team's strategy exploits highly aligned Cu(OH)2 nanotubes or nanobelts, grown on the substrate, as reaction sites for subsequent conversion into MOF crystallites. Cu(OH)2nanotubes are known to react with organic linkers with dimensions that are compatible with MOF materials — including 1,4-benzenedicarboxylate, one of the most widely studied MOF linkers.
