Phenyl-4-benzoyloxybenzoates with lateral methoxy substituent

Abstract

Three new series of compounds exhibiting nematic and smectic A phases have been prepared: 4-n-alkyl phenyl-3'-methoxy-4'-(4'-cyanobenzoyloxy) benzoate series, 4-cyanophenyl-3'-methoxy-4'-(4"-n-alkyl-benzoyloxy) benzoate series, and 4-n- alkylphenyl-3'-methoxy-4'-(4"-bromobenzoyloxy) benzoate series. The influence of lateral methoxy substituent on the mesomorphic properties is discussed.
