Abstract

Two microporous metal–organic frameworks (MOFs) based on zinc clusters, that is, [Zn₃(BDC)₂(HBDC)₂]·2DMA·4CH₃OH·2H₂O (1; H₂BDC = 1,4-dicarboxybenzene, DMA = N,N-dimethylacetamide) and [(CH₃)₂NH₂]₂[Zn₇(µ₄-O)₂(NDC)₆]·DMF·H₂O (2; H₂NDC = 1,4-naphthalenedicarboxylic acid, DMF = N,N-dimethylformamide), were synthesized by a solvothermal method. Both compounds possess three-dimensional porous skeletons with square channels and exhibit interesting blue fluorescence. Compound 1 consists of trinuclear Zn^IIbuilding units bridged by both BDC^2–and HBDC^–ligands, which results in the formation of a 2,8-connnected topological net (hex). Compound 2 features another 2,8-connected topological net (bcu) that is constructed by eight-connected Zn₇(µ₄-O)₂clusters and two-connected NDC^2–ligands. The solid-state and solvent-dependent fluorescence of the two MOFs revealed that 1 and 2 showed fluorescence enhancement effects in the presence of acetone and chloroform, respectively, which thereby demonstrates their potential as fluorescent sensors for selective sensing towards acetone and chloroform.
