LYOTROPIC LIQUID CRYSTAL SYSTEMS BASED ON BISACENAPHTHOPYRAZINOQUINOXALINE DERIVATIVES AND METHODS OF MAKING

摘要

A family of bisacenaphthopyrazinoquinoxaline derivatives of formula (I) and (II) is disclosed. These compounds are capable of forming liquid crystal systems that can produce optically isotropic or anisotropic films with desirable optical properties : (I), (II) wherein Ri, R2, Rs, R4, R5 and R& are each independently selected from -H, -SO3M, -OH, -NH2, -Cl, -Br, -I, -NO2, -F, -CF3, -CN, -COOH, -CONH2, alkyl, aryl, alkynyl, alkenyl, alkoxyl, alkylamino, phenoxyl, and phenylamino groups; M is one or more counter ions; j is the number of counter ions associated with the compound; and n is an integer in the range of 1 to S.
