LYOTROPIC LIQUID CRYSTAL SYSTEMS BASED ON AROMATIC TETRACARBOXYLIC BISBENZOIMIDAZOLE DERIVATIVES AND METHODS FOR MAKING

摘要

Compounds derived from aromatic tetracarboxyl bisbenzoimidazoles are disclosed. These compounds are capable of forming liquid crystal systems that can produce optically isotropic or anisotropic films with desirable optical properties. Formulae (I) or (II), or a salt thereof; wherein y is an integer in the range from 0 to about 4.
