Hollow tubular metal-organic frameworks: synthesis, characterization, and thermal properties.

In recent years, research targeting the synthesis of open or channel-containing metal-organic frameworks has interested chemists as such materials have found application in areas like gas absorbtion, size-selective separation, and heterogeneous catalysis. Our group has been successful in the synthesis of a new metal-organic open framework, namely [ZnF(AmTAZ)] solvents, using 3-amino-1,2,4-triazole (AmTAZ) and several Zn(II) salts as reactants. The framework, which consists of open-ended tubular channels arranged in a honeycomb-like array, is filled with solvents of crystallization that may be removed without framework decomposition. We have additionally synthesized two related compounds using the ligands 1,2,4-1H-triazole (TAZ) and 3,5-diamino-1,2,4-triazole (Am2TAZ). The solvothermal synthesis, structures, and thermal behavior of these materials will be discussed. * Supported by NSF Grant CHE:0314164 and Brin/EPScOR Grant 1P20RR16461
