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 ZnII building units bridged by both BDC2– 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)2 clusters and two‐connected NDC2– 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.
