以AgCl与柔性配体1,2-二(4-吡啶)乙烷(bpe)为原料,在1∶1的甲醇-水混合溶剂中超声反应合成了一个新的无机-有机杂化聚合物[Ag3Cl3(BPE)2]n(1),并对该配合物进行了元素分析、红外光谱分析、热重分析、发光测试以及晶体结构研究。配合物属于三斜晶系,P1空间群,a=0.998 8(2)nm,b=1.115 1(2)nm,c=1.269 5(3)nm,α=64.27(3)°,β=85.71(3)°,γ=86.70(3)°,V=1.269 7(5)nm3,Z=2。单晶结构分析表明,该化合物1含有一维的(Ag6Cl6)n链,双氮配体BPE进一步连接该一维链形成了二维双层结构。固体发光性能测试表明,该化合物在385 nm光激发下能发出峰值为525 nm的黄光。此外,热分析表明,该化合物热稳定性可达到170℃。
A novel inorganic-organic hybrid polymer was synthesized by the ultrasonic reaction of AgCl with bps, a flexible ligand, in a 1: 1 methanol-water mixed solvent [ Ag3Cl3 (BPE) 2] n (1) were synthesized and characterized by elemental analysis, IR, TG, luminescence and crystal structure. The complex belongs to the triclinic system with a = 0.998 8 (2) nm, b = 1.115 1 (2) nm, c = 1.269 5 (3) nm and α = 64.27 (3) °, γ = 86.70 (3) °, V = 1.269 7 (5) nm3, Z = 2. Single crystal structure analysis shows that the compound 1 contains one-dimensional (Ag6Cl6) n chain, and the dinitro ligand BPE further connects the one-dimensional chain to form a two-dimensional double-layer structure. Solid-state luminescence tests show that the compound emits yellow light with a peak of 525 nm at 385 nm. In addition, thermal analysis shows that the compound can reach a thermal stability of 170 ° C.
