Intelligent response organic room temperature phosphorescent material and preparation method and application thereof

Abstract

The application discloses an intelligent response organic room-temperature phosphorescent material and a preparation method and application thereof. The method comprises the following steps: dissolving a dipyridyl phosphor, a monomer and a crosslinking agent in a supersaturated solution obtained by melting a hydrated salt to obtain a mixed solution, adding an initiator into the mixed solution, stirring, and obtaining a precursor solution; and the monomer comprises acrylamide, acrylic acid or methyl methacrylate. The preparation method has the advantages of mild conditions, short preparation process, low cost, cheap and easily available raw materials, and the prepared material has the advantages of good stimulus response, long afterglow time, long phosphorescent lifetime and the like, and the material can realize response through touching, and has a wide application prospect in the fields of afterglow imaging, information encryption and anti-counterfeiting, warning or sensing.
