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.
