摘　　要：设计合成了一种新型的铜离子(Cu^(2+))罗丹明酰肼对二苯甲醛荧光分子探针(R)。检测了分子荧光探针对几种金属离子响应的紫外吸收光谱和荧光光谱。研究了它的光谱性能和对Cu^(2+)的识别作用,探针R加入Cu^(2+)时荧光加强,R加入Cu^(2+)之后,溶液由无色变为紫红色,探针R对Cu^(2+)具有专一的选择性。通过实验,考察和确定了荧光分子探针与Cu^(2+)响应的最佳pH和时间,在此基础上进行了定量检测,为了探究探针R和Cu^(2+)的实际配比,通过Job's plot的绘制实验方法,确定了Cu^(2+)与探针的物质的量比是1∶1,推测出了荧光探针R与Cu^(2+)络合物模型。A novel fluorescent molecular probe（R）of Cu^（2＋）luo danming hydrazide diphenylformal was designed and synthesized.UV absorption spectra and fluorescence spectra of several kinds of metal ions were detected by the probe.The spectral properties and the recognition for Cu^（2＋）of probe were studied.The fluorescence was enhanced when Cu^（2＋）was added to R.And the R was added to Cu^（2＋）,the solution changed from colorless to purple,and R had the selective selectivity to Cu^（2＋）.Through experiments,the optimal pH and response time of probe and Cu^（2＋）response were determined.On the basis the quantitative detection was carried out.In order to explore the actual ratio of probe R and Cu^（2＋）,through the experiment method Job＇s plot,the amount ratio of Cu^（2＋）and the probe was 1∶1,and metal ion complex was deduced by the fluorescence probe R.
