A novel Zn–MOF {[Zn₂(XN)₂(IPA)₂]·2H₂O}_n (1) (XN = 4′-(4-pyridine)4,2′:2′,4′′-terpyridine, IPA = isophthalic acid) was obtained and structurally characterized, and it exhibited high thermostability and chemical stability in various acid/base solutions (pH = 1–14) and common organic solvents. 1 can serve as the first recyclable luminescent sensor for selectively and sensitively recognizing acetylacetone with a detection limit of 0.25 ppm in aqueous solution. Importantly, 1 can be reused at least five times without a significant decrease in the luminescence intensity. Similarly, the Zn–MOF can also detect acetylacetone gas or that in organic solvents.

稳定的锌有机骨架，可检测水溶液中的乙酰丙酮†

新型Zn–MOF {[Zn ₂（XN）₂（IPA）₂ ]·2H ₂ O} _n（1）（XN = 4'-（4-吡啶）4,2'：2'，4''-获得了叔吡啶，IPA =间苯二甲酸，并进行了结构表征，在各种酸/碱溶液（pH = 1-14）和普通有机溶剂中均表现出很高的热稳定性和化学稳定性。图1中的传感器可以用作第一可回收发光传感器，用于选择性和灵敏地识别水溶液中的检出限为0.25 ppm的乙酰丙酮。重要的是1可以重复使用至少五次，而不会显着降低发光强度。同样，Zn-MOF也可以检测乙酰丙酮气体或有机溶剂中的气体。
