以4-(2-(4'-吡啶)乙炔)苯基芳香重氮盐为研究对象,在紫外光(250 W,245 nm)照射下,利用紫外.可见吸收光谱对该芳香重氮盐的乙腈溶液以及自组装单分子膜室温光解反应动力学进行了研究.确定了两种状态下的光解过程都符合一级反应动力学规律,并且溶剂极性使该重氮盐更容易发生光解反应.通过x射线光电子能谱(XPS)和电化学表征证实了4-(2-(4'-吡啶)乙炔)苯基芳香重氮盐经光解反应实现对石英片和氧化铟锡导电玻璃(ITO)表面的组装修饰,得到了通过共价键与基底联结的4-(2-(4'-吡啶)乙炔)苯自组装单分子膜,从而为其后基于有机.金属层层自组装技术构筑新型功能超薄膜奠定了基础.

In this paper,the photolysis kinetics of conjugate 4-(2-(4'-pyridinyl)ethynyl)benzene diazonium salt in acetonitrile and in solid-phase films was investigated by UV-Vis absorption spectroscopy after exposure to ultra-violet light(250 W,245 nm).Results show that the photolysis kinetics follows first order reaction kinetics and the polar acetonitrile solvent causes the diazonium group to photodecompose more easily.In addition,X-ray photoelectron benzene monolayer films which were anchored onto the surface of quartz and indium-tin-oxide(ITO)glass slides by covalent bonds.This method sets the stage for the successful design of organic-metal containing ultrathin films based on a layer-by-layer self-assembly technique.
