英文摘要： The aim of the present project is to investigate the preparation and properties of transparent ionogel thin films featuring the excellent luminescent properties of lanthanide ions, outstanding conductivity of ionic liquids and the good thermal stability of SiO2 gels.Silylated compounds that can be hydrolyzed and condensed to form organosilica gel and form luminescent complexes with lanthanide ions will be designed and synthesized.In addition, ionic liquid that can coordinate with lanthanide ions will also be designed and synthesized. In the lanthanide ion-coordinated ionic liquids, the silylated compounds will be hydrolyzed and condensed to form homogenoues and transparent solution ,which will be then fabricated into thin films by spin coating or dip coating method.Both ionic liquid and the organosilica gels are coordinated with lanthanide ions in the resulting thin films.The preparation conditions, luminescnece properties and conductivity will be investigated in detail. We believe our study will provide valuable data for the application of the ionogel films in device fabrications. Furthermore, our study not only can proved a facile way to obtain novelmultifunctional materials but also can realize the usitilizatio of lanthanide ions in high-tech fields.
