High sensitivity and selectivity detection of nitrobenzene based on luminescence technology requires high density of functional sites. Due to the abundant functional N sites and good solubility in solvents, triazine derivative ligands are potential to construct frameworks as luminescence detection agent. Herein, a Pt3O4 topology Zn-MOF (FJU-120) based on 2-amino-4,6-bis(4-pyridine)-1,3,5-triazine(DAPT)
基于发光技术的硝基苯的高灵敏度和选择性检测需要高密度的功能位点。由于丰富的功能 N 位点和良好的溶剂溶解性,三嗪衍生物配体有可能构建框架作为发光检测剂。在此,Pt 3 O 4拓扑结构 Zn-MOF ( FJU-120 ) 基于 2-amino-4,6-bis(4-pyridine) -1,3,5-triazine (DAPT) 和 1,3,5- Tris-(p-carboxyphenyl)benzo (H 3 BTB) 作为双配体合成用于选择性检测硝基苯。FJU-120在立方晶系和Pm n空间群中结晶,a =27.5191(9), b =27.5191(9),c =27.5191(9) Å, β =90°, V =20840(2) Å 3 , Z =90, Mr =448.72, Dc =0.429 g/cm 3 , F (000) = 2736。FJU-120在硝基苯存在下表现出选择性荧光猝灭行为,对应的常数为1124
