CARBAZOLYL POLYMERS FOR ORGANIC ELECTRONIC DEVICES |
摘要 |
Compositions comprising at least one phosphorescent organometallic compound and a polymer comprising structural units of formula (II) are useful in organic light emitting devices wherein R1, R2, and R4 are independently at each occurrence a C1-C20 aliphatic radical, a C3-C20 aromatic radical, or a C3-C20 cycloaliphatic radical; wherein R3 and R5 are independently selected from the group consisting of hydrogen, triphenylsilyl, t-butyl, mesityl, diphenyl phosphine oxide, and diphenyl phosphine sulfide; and a, b and d are independently 0 or an integer ranging from 1 to 3. |
