Patent

CA 2609135

The subject invention pertains to metal organic frameworks (MOF) having zeolite- net-like topology, their methods of use, and their modes of synthesis. The ZMOFs are produced by combining predesigned tetrahedral building, generated in situ using heterochelation, with polyfunctional ligands that have the commensurate angle and the required donor groups for the chelation. Each molecular building block is contrasted of a single metal ion and ligands with both heterochelation functionality and bridging functionality. Advantageously, zeolite-net-like MOFs of the subject invention are porous and contain large functional cavities, which is useful for encapsulating large molecules.

L'invention concerne des structures organométalliques (MOF) présentant une topologie de type réseau zéolithe, des procédés d'utilisation de ces structures organométalliques, ainsi que leurs modes de synthèse. Ces ZMOF sont produites par combinaison d'unités de construction tétraédriques préconçues, générées in situ par hétérochélation, avec des ligands polyfonctionnels présentant l'angle correspondant et les groupes donneurs requis pour la chélation. Chaque bloc de construction moléculaire comporte un ion métallique unique et des ligands présentant simultanément la fonction d'hétérochélation et la fonction de pontage. De manière avantageuse, les MOF de type réseau zéolithe selon l'invention sont poreux et comportent de grandes cavités fonctionnelles servant à encapsuler des molécules de grandes dimensions.
