A stable pillar-layer NaI-organic framework, [Na2(DCPB)∙(H2O)2]n (namely 1), was rationally designed and synthesized by the assemble process of NaI and 1,3-di(4'-carboxyl-phenyl)benzene (H2DCPB). Benefiting from the luminescent property and high stability in water, the as-synthesized 1 is a potential multi-responsive luminescent sensor material toward Cr2O72-, Fe3+, and nitrofurazone (NFZ) in water. Ground 1 not only has the excellent detectability and selectivity but also possesses outstanding stability and circularity. The calculated Ksv values of 1 are 8.8×103 for Fe3+, 9.9×103 for Cr2O72-, and 2.7×104 M-1 for NFZ in aqueous solutions, respectively. Furthermore, 1 is able to accurately detect NFZ in real bovine serum samples through luminescence detection technology.

合理设计和合成稳定的支柱层NaI有机框架，作为水溶液中的多响应发光传感器。

通过NaI和1,3-di（4'-羧基-）的组装过程，合理设计合成了一种稳定的柱状NaI有机骨架[Na2（DCPB）∙（H2O）2] n（即1）。苯基）苯（H2DCPB）。得益于在水中的发光特性和高稳定性，合成后的1是潜在的针对水中Cr2O72-，Fe3 +和呋喃西林（NFZ）的多响应发光传感器材料。地面1不仅具有出色的可检测性和选择性，而且具有出色的稳定性和圆度。对于水溶液，Fe3 +的计算得出的Ksv值1分别为8.8×103，Cr2O72-的9.9×103和NFZ的2.7×104 M-1。此外，1能够通过发光检测技术准确检测实际牛血清样品中的NFZ。
