N2 - 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 ZnIIbuilding 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)2clusters 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.
