Luminescent MOFs are ideal tools for sensing applications owing to the ability to trap analytes. A series of seven novel polymeric compounds i.e. [Cd(1,4-BDC) (Pro) (H₂O)]_∞, [Cd(1,4-BDC) (L-Trp) (H₂O)]_∞, [Cd(1,4-BDC) (L-Ala) (H₂O)]_∞, [Cd(1,4-BDC) (L-Phe) (H₂O)]_∞, [Cd(1,4-BDC) (L-Val) (H₂O)]_∞, [Cd(1,4-BDC) (L-Leu) (H₂O)]_∞, [Cd(1,4-BDC) (L-Arg) (H₂O)]_∞ were synthesized from layered structure Cd-MOF using the technique of postsynthetic modification. The postsynthetic modification was performed on metal center through the utilization of pure l-amino acids Proline(Pro), Tryptophan(Trp), Alanine(Ala), Phenylalanine (Phe). Valine(Val), Leucine(Leu) and Arginine (Arg). The post synthetically modified compounds were characterized by FTIR, TGA, ¹H NMR, Elemental analysis, PXRD and UV–visible spectroscopy. Luminescence properties were investigated in solid-state, which shows that all the novel compound has higher emission intensity as compared to parent MOF.

由于具有捕获分析物的能力，发光MOF是理想的传感应用工具。一系列七个新型聚合化合物，即[Cd（1,4-BDC）（Pro）（H ₂ O）] _∞，[Cd（1,4-BDC）（L-Trp）（H ₂ O）] _∞， [Cd（1,4-BDC）（L-Ala）（H ₂ O）] _∞，[Cd（1,4-BDC）（L-Phe）（H ₂ O）] _∞，[Cd（1,4 -BDC）（L-Val）（H ₂ O）] _∞，[Cd（1,4-BDC）（L-Leu）（H ₂ O）] _∞，[Cd（1,4-BDC）（L- Arg）（H ₂ O）] _∞使用后合成修饰技术从层状结构Cd-MOF合成了Cd-MOF。通过利用纯1-氨基酸脯氨酸（Pro），色氨酸（Trp），丙氨酸（Ala），苯丙氨酸（Phe）对金属中心进行后合成修饰。缬氨酸（Val），亮氨酸（Leu）和精氨酸（Arg）。经过合成修饰的化合物通过FTIR，TGA，¹ H NMR，元素分析，PXRD和UV-可见光谱进行表征。在固态下研究了发光性质，这表明与母体MOF相比，所有新化合物均具有更高的发射强度。
