ABSTRACT:
The invention provides compounds of formula Iwherein R is H or alkyl;R1, R2, and R4are independently at each occurrence a C1-C20aliphatic radical, a C3-C20aromatic radical, or a C3-C20cycloaliphatic radical; R3and R5are independently at each occurrence hydrogen, a C1-C20aliphatic radical, a C3-C20aromatic radical, or a C3-C20cycloaliphatic radical; anda, b and d are independently 0 or an integer ranging from 1 to 3. The invention further provides polymers derived from compounds of formula I, said polymers may be polyesters, polyethers, polycarbonates, polyestercarbonates, polyetherketones, polyethersulfones, and the like. Compounds and polymers of the invention find use in light emitting devices.
