-
Paragraph 0022-0024, (2021/07/28)
The invention belongs to the technical field of photoelectric display devices, and particularly relates to a naphthoselenodiazole delayed-fluorescence material and a preparation method thereof. The naphthoselenodiazole delayed-fluorescence material provided by the invention has a structural formula as shown in a formula (I) which is described in the specification. The invention also provides a preparation method of the naphthoselenodiazole delayed-fluorescence material. The preparation method comprises the following steps: carrying out a substitution reaction on a compound as shown in the formula (II) and a compound as shown in the formula (III) to prepare the compound as shown in the formula (I). The naphthoselenodiazole delayed-fluorescence material and the preparation method thereof provided by the invention solves the technical problems that existing red TADF materials are relatively difficult to synthesize and device efficiency is not high.
