Abstract
The invention relates to polymers useful in optoelectronic devices and comprising structural unit of formula I: wherein R1 and R2 are independently at each occurrence, hydrogen, a C1-C20 aliphatic radical, a C3-C20 aromatic radical, or a C3-C20 cycloaliphatic radical; R3 is H or alkyl; a and b are, independently at each occurrence 0, or an integer ranging from 1 to 3; and Ar is a direct bond or aryl.
