| titleOfInvention | Pyridazinone derivative, preparation method and organic electroluminescence element |
| abstract | The invention discloses a pyridazinone derivative, a preparation method and an organic electroluminescence element. The pyridazinone derivative has a structure represented by formula (1) or formula (2), wherein: Ar 1 and Ar 2 are each independently a substituted or unsubstituted arylene group; R 1 and R 2 are each independently selected from From: hydrogen, alkyl with 1-8 carbon atoms, cyano, aryl with 6-40 carbon atoms or heteroaryl with 2-40 carbon atoms, amino, -NR 3 R 4 ; R 3 , R 4 are each independently substituted or unsubstituted aryl; m, n, k are each independently selected from 1, 2 or 3; the pyridazinone derivative has good electron transport and hole blocking properties, and can be Used as electron transport material or hole blocking material in organic electroluminescence elements, |
