摘要
以苯并咪唑(HL^1)和3,6-二氯哒嗪在钠催化下反应制得配体3-氯-6-(苯并咪唑-1-基)哒嗪(L^2);采用溶液法和水热法,L^1分别与含有银、铜过渡金属盐反应合成了3种新的有机金属苯并咪唑配合物[Ag L^1]n(1),[Cu_4(HL^1)_4(O)(Cl)_6](2)和{[Cu(HL^1)_2]·SiF_6}(3);采用溶液法,L^2与Zn(NO_3)_2·6H_2O经配位反应合成了配合物{[Zn(L^2)_3(NO_3)]NO_3}(4),其结构经IR,元素分析和X-射线单晶衍射表征。结果表明:1通过苯并咪唑桥连形成一维链状结构,2由苯并咪唑和氯离子桥接形成四核结构,3和4均显示一个单核结构,3的金属中心原子采用二配位构型,4的金属中心原子采用四配位构型。此外,研究了配体HL^1与1,及配体L^2与4的荧光性能。结果表明:与HL^1相比,1的最大发射波长发生了红移;而4相对于配体L^2其最大发射峰发生明显蓝移。
3-Choloro-6-（ benzoimidazol-1 -yl） pyridazine （ L2 ） was synthesized by reaction of benzimid- azole （ HL1 ） with 3,6-dichloropyridazine catalyzed by Na. Three new complexes, [ AgL1 ] n （1）, [ Cu4 （HL1）4（O）（Cl）6]（2） and {[Cu（HL1）2] · SiF6t （3） were synthesized by reaction of HL1 with silver and copper salts via solution method and the hydrothermal method. One new complex, { [ Zn （ L2 ） 3 （ NO3 ） ] · NO3 / （4）, was synthesized by reaction of L2 with Zn （ NO3 ） 2 · 6H2O. The struc- tures were characterized by IR, elemental analysis and X-ray single crystal diffraction analysis. The re- suits showed that 1 shows a one-dimensional chain structure bridged by benzimidazole, 2 displays a four-nuclear structure bridged by benzimidazole and C1- anions, 3 and 4 feature a mononuclear struc- ture, 3 shows a four-coordinated geometry, 4 shows a two-coordinated geometry. Moreover, photolumi- nescence properties of ligands HL1, L2 and complexes 1 and 4 were investigated. The maximum emis- sion wavelength of 1 showed a red shift compared with that of the ligand HL1, however, the maximum emission peak of 4 showed a blue shift compared with that of the ligand L2.
