Claim 5:
6. A preparation method for preparing the thermally activated delayed fluorescent green light polymer material according to claim 1, comprising following steps of:
adding a benzene compound with a boron ring structure, a benzene compound with a nitrogen ring structure, palladium acetate, and tri-tert-butyl phosphine tetrafluoroborate into a reaction bottle, wherein in the benzene compound with the nitrogen ring structure, the nitrogen ring structure forms an amino group; and a chemical structural formula of the benzene compound with the boron ring structure is as follows:, placing the reaction bottle into a glove box, and adding NaOt-Bu to the reaction bottle in the glove box, and further adding toluene under an argon atmosphere, followed by reacting at 100-140° C. for 20 to 30 hours, and cooling to a room temperature to obtain a mixed solution; and
pouring the mixed solution into an ice water, extracting organic phases from the mixed solution multiple times with dichloromethane, combining the organic phases extracted by the multiple times, and separating and purifying the extracted organic phases by a silica gel chromatography to obtain the thermally activated delayed fluorescent green light polymer material.
