Mesomorphic Behavior of N,N’-bis(4-(4-Alkoxybenzoyloxy)Benzylidene)-3,3’-Diaminodiphenylsulfones
A new series of sulfur ligated siamese twin mesogens, N,N’-bis[4-(4-alkoxybenzoyloxy)benzylidene]3,3’-diaminodiphenylsulfones has been studied for the thermotropic phase transition behavior. A stable or metastable nematic phase is exhibited by the methoxy to tetradecyloxy derivatives and a metastable smectic C phase by the dodecyloxy to octadecyloxy derivatives.
