The invention provides electroluminescent materials using truxenone as an
electron acceptor and an application of the electroluminescent materials, and belongs to the field of
organic electroluminescence. The derivatives use the truxenone as the
electron acceptor, and
carbazole, 1,3,6,9-tetramethylcarbazole, 3,6-di-tert-butylcarbazole, 3-carbazolylcarbazole, 9,9-dimethylacridine,
phenoxazine and
phenothiazine as
electron donors. A synthetic method of the series of compounds comprises the following steps: performing a
coupling reaction by using 5-bromo-1-
indenone as a
raw material, performing an oxidation reaction, and performing a Buchwald-Hartwig
coupling reaction to obtain the truxenone substituted by different
electron donor groups. The series of compounds have strong absorption in theultraviolet-visible light regions, a dilute solution of the compounds emits strong
fluorescence, the emitting color is orange-red or red, and the compounds can be used as light-emitting materials to be applied to organic light-emitting diodes.
