Title:
カルバゾール誘導体、発光素子および電子機器
Document Type and Number:
Japanese Patent JP4558510
Kind Code:
B2
Abstract:
The problem of the present invention is to provide a carbazole derivative which has an excellent heat resistance and can be formed into a film without crystallization. Also, a problem is to produce an organic semiconductor element, a light emitting element and an electronic device by employing the carbazole derivative. For the purpose, a novel carbazole derivative represented by following general formula (1) is provided: (in the formula, I represents a core carbazole (G0) illustrated by general formula (2), Z represents an internally branched carbazole (G1 to Gn-1) illustrated by general formula (3), E represents an end carbazole (Gn) illustrated by general formula (4), n represents an integer showing generation number of dendrimer, X1 represents hydrogen, halogen, a cynano group, an alkyl group, an aryl group, a heterocyclic residue or the like, X2 and X3 in (G(n-m)-1) (provided, n-m>=1) make a covalent bond with X4 in (G(n-m)), and each of R1 to R8 represents independently hydrogen, halogen, a cynano group, an alkyl group, a dialkylamino group, a diarylamino group, a heterocyclic residue or the like).
