Metal-organic frameworks (MOFs) have presented potential for detection of specific species and catalytic application due to their diverse framework structures and functionalities. In this work, two novel pillar-layered MOFs [Cd(DPA)(NTB)(HO)]·n(DPA·5DMA·HO) () and [Cu(DPA)(OBA)]·n(2.5DMF·HO) () [DPA = 2,5-di(pyridin-4-yl)aniline, HNTB = 4,4',4''-nitrilotribenzoic acid, HOBA = 4,4'-oxydibenzoic acid, DMA = N,N-dimethylacetamide, DMF = N,N-dimethylformamide] were successfully synthesized and structurally characterized. Both and have three-dimensional framework structures. The fluorescent property of makes it possible for sensing specific amino acid such as L-glutamic acid (Glu) and L-aspartic acid (Asp). While MOF was found to be suitable for photocatalytic degradation of Rhodamine B (RhB) in the presence of HO. The results imply that MOFs are versatile and metal centers are important in determining their properties.

金属-有机骨架（MOFs）由于其多样的骨架结构和功能，在特定物种的检测和催化应用方面具有潜力。在这项工作中，我们成功合成并结构表征了两种新型的柱状层状 MOFs [Cd(DPA)(NTB)(HO)]·n(DPA·5DMA·HO) () 和 [Cu(DPA)(OBA)]·n(2.5DMF·HO) () [DPA = 2,5-二（吡啶-4-基）苯胺，HNTB = 4,4',4''-三羧酸基三苯胺，HOBA = 4,4'-氧二苯甲酸，DMA = N,N-二甲基乙酰胺，DMF = N,N-二甲基甲酰胺]。和都具有三维骨架结构。具有荧光性质，使其能够感应特定的氨基酸，如 L-谷氨酸（Glu）和 L-天冬氨酸（Asp）。而 MOF 则被发现适合在 HO 的存在下光催化降解 Rhodamine B（RhB）。结果表明，MOFs 具有多功能性，金属中心在确定其性质方面起着重要作用。
