Intrinsic long-life organic room-temperature phosphorescent material as well as preparation method and application thereof

The invention discloses an intrinsic long-service-life organic room-temperature phosphorescent material and a preparation method and application thereof.The material is obtained by polymerizing a polymer monomer and a phosphorescent monomer and then sequentially conducting alcoholysis and crosslinking, by increasing the rigidity of a molecular structure step by step, the step-by-step confining effect of the dual functions of a covalent bond and a hydrogen bond network is achieved, and the intrinsic long-service-life organic room-temperature phosphorescent material is obtained. The luminescent process of long-life room-temperature phosphorescence from nothing to existence and then to strong is realized, and the phosphorescence life is prolonged by thousands of times. The method is simple to operate and low in production cost, has good universality, provides a new strategy for designing a long-life room-temperature phosphorescent material, and has good application prospects in the fields ...
