| 摘要: 以5-（（萘-1-基甲基）氨基）间苯二甲酸（H2L）与Cd2+通过溶剂热法合成出二维层状金属有机骨架[Cd （L）（H2O）]·H2O （1）。结构分析显示层与层之间通过π-π和C—H…π相互作用形成了三维超分子结构。值得注意的是，1在酸性条件下发光会显著增强，这可用于选择性的检测酸性氨基酸，1对天冬氨酸和谷氨酸的检测限分别为3.88和5.43 μmol·L-1。 |

| Abstract: A 2D layered metal-organic framework[Cd(L)(H2O)]·H2O (1) was synthesized from 5-((naphthalen-1-ylmethyl)amino)isophthalic acid (H2L) and Cd2+ by a solvothermal method. Structural analysis reveals that the adjacent layers are connected by π-π stacking and C-H…π interactions to form a 3D supramolecular structure. Notably, the luminescence of 1 was significantly enhanced under acidic conditions, which can be used for selective and sensitive detection of acidic amino acids. The limits of detection of 1 for aspartic acid and glutamic acid were 3.88 and 5.43 μmol·L-1, respectively. |
