Issue Date: | 2010 | Publisher: | Wiley-Blackwell | Citation: | Chemistry - A European Journal 16(12): 3833-3841 (2010) | Abstract: | A one-step synthesis of octakis(3-azidopropyl)octasilsesquioxane from commercially available octakis(3-aminopropyl)octasilsesquioxane has been developed through a highly efficient diazo-transfer reaction under very mild conditions. Nonaflyl azide is shown to be a safer, cheaper, and more efficient reagent for this transformation than the better known and generally used diazo-transfer reagent triflyl azide. Octakis(3-azidopropyl)octasilsesquioxane is an excellent nanobuilding block that can be readily octafunctionalized with a range of terminal alkynes by copper(I)-catalyzed 1,3-dipolar azide–alkyne cycloaddition to provide new functional nanocages, maintaining a perfect 3D cubic symmetry. The mildness, simplicity, and efficiency of this approach have been demonstrated in the preparation of a glyco-polyhedral oligosilsesquioxane (POSS) conjugate and a BODIPY–POSS cluster (BODIPY=boron dipyrromethene). | Description: | 9 páginas, 1 figura, 1 esquema, 2 tablas | Publisher version (URL): | http://dx.doi.org/10.1002/chem.200902422 | URI: | http://hdl.handle.net/10261/31022 | DOI: | 10.1002/chem.200902422 | ISSN: | 0947-6539 |
