Construction Of Luminescent Coordination Polymer With Electron-rich System And Its Application In The Detection Of Nitro Compounds/Metal Ions

This thesis focuses on the research direction of Luminescent coordination polymer(LCP),the electron-rich ligands and transition metals or rare earth metals to synthesize three new LCPs under hydrothermal conditions,and further explore its fluorescence detection performance and mechanism of action for nitro compounds and metal ions,the main works are as follows:(1)Two new structures of complex 1 and 2 were synthesized by solvothermal method using 4,4-dipyridyl diphenyl ether(BDPDE)as main ligands,succinic acid or phthalic acid as auxiliary ligands,and their fluorescence properties were deeply explored.Complex 1 can effectively detect the presence of 2,4,6-trinitrophenol in ethanol solution and the result can be recycled.Complex 2 can detect nitro compounds and metal ions with high selectivity in aqueous solution,especially for2,4,6-trinitrophenol and Fe³⁺,showing highly selective fluorescence recognition performance.(2)On the basis of the complex 3 which was synthesized by H₂L and cadmium,a new type of LCP material 4 was synthesized by mixing and heating with metal europium,and the preliminary fluorescence sensing properties were investigated.It was found that complex 4 exhibits fluorescence recognition performance for2,4,6-trinitrophenol and Fe³⁺.Figure[55]Table[3]Reference[87]...
