Abstract

The invention belongs to the technical field of preparation of an inorganic and organic hybrid material with a fluorescence property and particularly relates to an ion exchange method for preparing an aggregation induced emission (AIE) group functionalized laminar zirconium phosphate material. Cation groups containing water-soluble AIE molecules are intercalated into the material by an ion exchange intercalation mode by using zirconium phosphate with a laminar structure as a framework element and organic amine as a pre-swelling agent, so that the inorganic and organic hybrid material with the strong fluorescence can be obtained. The method is suitable for various laminar zirconium phosphate materials which contain the AIE water soluble molecules of the cation groups and have the anion framework structures. The interlamellar spacing and the luminance of the zirconium phosphate can be effectively controlled by changing the varieties and the adding amounts of the AIE molecules or the pre-swelling agents, so that the material can be widely applied to the fields of medicine delivery, bioimaging, explosive detection and the like.
