BIS-CARBAZOLMONOMERE UND -POLYMERE

摘要

The invention relates to compounds of formula I 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; R³ and R⁵ are independently at each occurrence hydrogen, a C₁-C₂₀ aliphatic radical, a C₃-C₂₀ aromatic radical, or a C₃-C₂₀ cycloaliphatic radical; and a, b and d are independently 0 or an integer ranging from 1 to 3. The invention further relates to polymers derived from compounds of formula I. The polymers may be polyesters, polyethers, polycarbonates, polyestercarbonates, polyetherketones, or polyethersulfones. Compounds and polymers of the invention find use in light emitting devices.
