These monomers were polymerized in the presence of 2,2'-azoisobutyronitrile as initiator in THE All monomers and polymers show cholesteric behavior and a broad chiral smectic C* phase. As the spacer length increases, the phase transition temperature is lowered and the polymers show higher phase transition temperatures and improved mesophase stabilities compared to the corresponding monomers.
