以4-(2-(4′-吡啶)乙炔)苯基芳香重氮盐为研究对象,在紫外光(250W,245nm)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.
The aromatic diazonium salt of 4- (2- (4’-pyridyl) acetylene) was used as the target of this study. The UV spectrum of the aromatic diazonium salt in acetonitrile (250 W, 245 nm) As well as the kinetics of self-assembled monolayers at room temperature photolysis were studied. It was confirmed that the photolysis processes in both states were in accordance with the first-order reaction kinetics and that the solvent polarity made the diazonium salt more susceptible to photolytic reaction The photolysis reaction of 4- (2- (4’-pyridyl) acetylene) phenyl-aromatic diazonium salt on quartz glass and indium tin oxide conductive glass (XRD) was confirmed by XPS and electrochemical characterization (4- (2- (4’-pyridyl) acetylene) benzene self-assembled monolayer bonded to the substrate via covalent bond, so that it can be used for the subsequent self-assembly based on the organic-metal layer Build a new type of functional ultra-thin film laid the foundation.
