设计合成了一个含有苯并噻二唑结构单元的对三联苯二羧酸配体H21,将其与二甲基修饰的对三联苯二羧酸配体H22以物质的量比1∶1在N,N-二甲基甲酰胺溶剂中混合后;在醋酸存在条件下,与Zr Cl4发生溶剂热反应而得到金属有机骨架Ui O-68-S.X射线粉末衍射表明该金属有机骨架具有Ui O-68类型的框架结构;77 K温度下,氮气吸附等温曲线表明其具有较高的孔隙和比表面.在空气气氛和蓝光LED的照射下,金属有机骨架Ui O-68-S可作为硫醚选择性氧化以及芳香硼酸羟基化的非均相光催化剂.
A p-terphenyl-dicarboxylic acid ligand H21 containing benzothiadiazole structural units was designed and synthesized, which was reacted with dimethyl-modified p-terphenyl dicarboxylic acid ligand H22 in a molar ratio of 1: 1 to N , N-dimethylformamide solvent; in the presence of acetic acid solvothermal reaction with Zr Cl4 to obtain a metal organic framework Ui O-68-SX-ray powder diffraction shows that the metal organic framework has a Ui O-68 Type of framework structure; 77 K temperature, nitrogen adsorption isothermal curve shows that it has a higher porosity and specific surface in the air and blue LED irradiation, the metal organic framework Ui O-68-S can be used as a thioether selectivity Oxidation and aromatic boronic acid hydroxylation heterogeneous photocatalyst.
