| abstract |
The present invention provides a pyrene-containing compound having a structure shown in formula I, formula II or formula III; wherein, R 1 , R 2 , R 3 , R 4 and R 5 are independently selected from hydrogen, substituted or unsubstituted C 1 -C 60 alkyl, substituted or unsubstituted C 6 -C 30 aryl. The pyrene-containing compound provided by the invention has higher luminous efficiency and longer lifespan. The invention provides a method for preparing a pyrene-containing compound, comprising: reacting a compound having a structure shown in formula A-1 with a compound having a structure shown in formula B-1 to obtain an intermediate product; combining the intermediate product with formula C Compounds of the shown structures are reacted to give pyrene-containing compounds. The present invention also provides an organic light-emitting device, comprising an anode, a cathode, and an organic compound layer arranged between the anode and the cathode, the organic compound layer comprising the pyrene-containing compound described in the above technical solution. |
