Abstract

A new coordination polymer was synthesized under hydrothermal condition, namely [Zn(Bpy)(DHTA) 0.5 ] n (DHTA = 2,5-dihydroxy-1,4-terephthalic acid tetra-anion, Bpy = 2,2'-bipyridine). There is one Zn(II) ion in [Zn(Bpy)(DHTA) 0.5 ] n , the center metal Zn(II) ion is five-coordinated. It can remain stable at temperatures as high as 380 o C, and a sharp drop in weight is found in the temperature range of 380 - 570 o C. The calculation results show that the residual is zinc(II) oxide (ZnO). The emission peak of complex 1 is at 365 nm (λ ex = 316 nm). The photoluminescence results suggest that complex 1 has potential as a new luminescence material. At the same time, in the luminescence explorations experiments, complex 1 showed a high degree of selectivity and sensitivity to organic solvents (DMK) and metal ions (Fe 3+ ).
