A new series of Schiff base esters,4-(dimethylamino)benzylidene-4’-alkanoyloxyanilines containing even number of carbons at the end group of the molecules(C_(n-1)H_(2n-1)COO,n = 6,8,10,12,14,16,18) were synthesized.The present compounds were monotropic liquid crystals.It was also found that the end groups of the molecules had effect on the mesomorphic properties.
A new series of Schiff base esters, 4- (dimethylamino) benzylidene-4’-alkanoyloxyanilines containing even number of carbons at the end group of the molecules (C n-1 H 2n-1 COO n = 8,10,12,14,16,18) were synthesized. The present compounds were monotropic liquid crystals. It was also found that the end groups of the molecules had effect on the mesomorphic properties.
