The project will focus on self-healable lanthanide complex-based organic-inorganic hybrid materials of highly efficient luminescence prepared under aqueous conditions. Novel positively charged lanthanide complexes will be designed and synthesized, which are soluble and can self-assemble into spherical micelles showing sufficient luminescence in water. The amphiphilic micelles will be used as effective and luminescent “molecule binder” to the exfoliated nanosheets precoated with sodium polyacrylate into networks via electrostatic interactions, producing lanthanide complex-based organic-inorganic hybrid materials with good mechanical properties, fast self-healable ability and high luminescence efficiency. In this project, we will explore prepare procedure and the mechanism responsible for the formation of the luminescent self-healable materials, study luminescent properties and self-healing ability, and investigate luminescence mechanism and self-healing mechanism. This project will realize the simple and fast preparation of self-healable and highly luminescent lanthanide complex-based organic-inorganic hybrid materials under aqueous conditions, provide data and technology for the application of lanthanide complex-based organic-inorganic hybrid materials in fabricating flexible optoelectronic device.This study is of high importance for developing new preparation strategy and procedure for obtaining new multifunctional materials. Furthermore, it can also help us make use of lanthanide-based materials in new and high technological fields as well as convert the advantages of lanthanide resource to economical and technological ones.
