摘　　要：以水合肼和对二甲氨基苯甲醛为原料设计合成了双对二甲氨基苯甲醛缩连氮(1),经元素分析、1H-NMR及质谱对其结构进行了表征。在甲醇-水(V/V=4:1)混合溶剂中采用UV-Vis光谱法和荧光光谱法研究了化合物1对H+、Li+、Na+、K+、Mg2+、Ca2+、Mn2+、Co2+、Ni2+、Zn2+、Cd2+、Hg2+及Cu2+的选择性识别性能。结果表明,化合物1的紫外-可见光谱仅对H+有特殊的选择敏感性;其荧光光谱对H+、Mn2+和Co2+有显著的识别传感能力,三种离子均可有效地猝灭化合物1的荧光。根据Stern-Volmer公式,Mn2+和Co2+对化合物1荧光的影响属于动态猝灭过程。Bis( p-dimethylaminobenzaldehyde) azine( 1) was synthesized starting from p-dimethylamino-benzaldehyde with aqueous hydrazine,and its structure was characterized by elementary analysis,1H-NMR and mass spectra. The influence of H+,Li+,Na+,K+,Mg2 +,Ca2 +,Mn2 +,Co2 +,Ni2 +,Zn2 +,Cd2 +,Hg2 +and Cu2 +on the spectra of compound 1 were investigated by the UV-vis and fluorescence spectrum method in methanol-water mixed solvent. The result indicated that the UV-vis spectra of compound 1 only behaved special selectivity and sensitivity to H+; however,the fluorescence spectra of this compound behaved obvious recognition and sensing behavior to H+,Mn2 +and Co2 +. the fluorescence of compound 1 was efficiently quenched by H+,Mn2 +and Co2 +. On the basis of the Stern-Volmer formula,the effects of Mn2 +and Co2 +on compound 1 belongs to the dynamic quenching of fluorescence.
