The invention provides compounds of formula I
wherein R is H or alkyl;
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 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.
