Abstract
Two homologous series are synthesized by fixing a rigid 4-methyl phenyl azo group to resorcinol moiety. In series I one phenolic -OH group is alkylate d whereas, in series II both the phenolic -OH groups are alkylated. Monoeth ers of series I having free lateral hydroxy group due to strong hydrogen bo nding, exhibit nematic mesophases whereas, diethers of series H are non-mes ogenic.
