Abstract : In an attempt to synthesize side chain liquid crystalline polymers containing NLO active moieties, a number of p-substituted aromatic azomethine phenols with donor-acceptor substituents such as N=C and N02 were prepared and incorporated into a polymer chain as side groups. Liquid crystalline properties of intermediate compounds composed of such moieties were explored separately and in mixtures. Phase diagrams were established. These intermediate compounds of M2C8 and M5C8 show interesting mesogenic properties. Methacrylic esters with such moieties were also synthesized. Homopolymer and copolymer systems with donor-acceptor substituents were obtained. Such copolymers also display liquid crystalline properties.
