Luminescent triarylboron-functionalized zinc carboxylate metal-organic framework

A luminescent triarylboron ligand functionalized with three carboxylic groups has been synthesized and fully characterized. Its use in boron-containing metal-organic frameworks (B-MOFs) has been demonstrated by the synthesis and isolation of a Zn(II)B-MOF compound (B-MOF-1). The crystals of B-MOF-1 belong to the cubic space group F432 with 8-fold interpenetrated networks and ∼21% void space. B-MOF-1 exhibits blue fluorescence and is capable of modest gas sorption of N(2), argon, and CO(2).
