Zirconium Materials from Mixed Dicarboxylate Linkers: Enhancing the Stability for Catalytic Applications

[EN] We report the synthesis of two series of zirconium-based metal-organic frameworks from solutions composed of a mixed-ligand system (naphthalene dicarboxylic acid/4-amino-2,6-naphthalenedicarboxylic acid or [1,1'-biphenyl]-4,4'-dicarboxylic acid (BPDC)/2-amino-[1,1'-biphenyl]-4,4'-dicarboxylic acid). Materials synthesized with low loadings of functionalized linkers exhibit higher long-term chemical stability and similarly high thermal stability relative to those with 100% amino linkers. These materials and their corresponding rhodium derivatives prove excellent catalysts in one-pot reactions. Moreover, the recycling experiments demonstrate an interesting prospect for the long-term reusability of these catalysts.This work was supported by MINECO of Spain (Project MAT2011-29020-C02-02, Consolider-Ingenio 2010-CSD-0050-MULTICAT).
