A new series of liquid crystalline (LC) monomers based on an unsymmetrically disubstituted cyanostilbene containing hydroxy- and carboxylic acid groups has been synthesized and characterized. The monomers could be polymerized in the presence of N,N-dicyclohexylcarbodiimide and 4-pyrrolidinopyridine to give a new class of main-chain LC polymers which may have potential applications in the field of non-linear optics.
