Abstract

The invention belongs to the technical field of triazine polymers, and relates to a triazine polymer and a preparation method thereof. The triazine polymer is obtained by mixing a compound containing a triazine ring with polyhydric alcohol sodium salt, conducting condensation polymerization through a Williamson ether synthesis method and conducting washing; the compound containing the triazine ring comprises a halogenated s-triazine compound, and the halogenated s-triazine compound comprises tripolychloroazine or 2-hydroxy-4, 6-dichloro s-triazine; the prepared triazine polymer has excellent phosphorescence quantum yield, long phosphorescence lifetime and unique luminescence characteristic, still has good long afterglow characteristic in a high-temperature environment, and utilizes the limitation of a special long-chain entanglement structure of the polymer on a non-radiation process to improve the luminous efficiency of the triazine polymer. The attenuation speed of the afterglow life along with the environment temperature is greatly slowed down; and the obtained triazine polymer not only can be used for photoelectric functional materials, but also can be used as an organic chemical intermediate, and has wide application in the fields of multiple encryption, anti-counterfeiting and the like.

Description

technical field [0001] The invention belongs to the technical field of triazine polymers, in particular to a triazine polymer and a preparation method thereof. Background technique [0002] The s-triazine ring is an aromatic benzene-like ring compound composed of 3 carbon atoms and 3 nitrogen atoms. Among them, due to the influence of the lone nitrogen atom on electrons, compared with the benzene ring, the electron cloud density on the s-triazine ring is higher, making its photoelectric performance stronger. Therefore, compounds with a s-triazine ring structure have been obtained in the field of organic optoelectronics. extended application. [0003] For example, patent CN201611206304.9 discloses a compound with triazine as the core and its organic electroluminescent device. A carbazole with substituted side groups can be connected to the s-triazine ring to obtain a class of electroluminescent s material. On the other hand, other modification groups can be connected to th...
