Influence of structure of two ring ester on the induction of smectic Ad Phase in bicomponent mixtures containing a compound with virtual Ad phase
Mixtures of 4-cyano-4′-hydroxyazobenzene 4-n-octyloxybenzoate (8OBCAB) - constant compound and 4′-X-phenyl 4-n-decylbenzoate or 4′-X-phenyl 4-n-decyloxybenzoate (10.X, 10.O.X) - the variable compound in which X refers to the terminal group CN, NO 2 , NCS, COCH 3 , Cl or F, were studied by thermomicr...

| description | Mixtures of 4-cyano-4′-hydroxyazobenzene 4-n-octyloxybenzoate (8OBCAB) - constant compound and 4′-X-phenyl 4-n-decylbenzoate or 4′-X-phenyl 4-n-decyloxybenzoate (10.X, 10.O.X) - the variable compound in which X refers to the terminal group CN, NO
2
, NCS, COCH
3
, Cl or F, were studied by thermomicroscopic and X-ray methods. The influence of the terminal groups on the kind of phases and their miscibility was observed. The enhancement of the smectic A
d
phase together with the appearance of the nematic gap between A
d
and A
1
smectic phases and re-entrant nematic phase were observed in mixtures with high polar compounds (-CN, -NO
2
). Complete miscibility together with an increase of smectic A phase persistence were observed in mixtures with medium polar compounds (-NCS, -COCH
3
). Additive miscibility was observed in mixtures with low polar compounds (-Cl, F). |
