Abstract
Phase diagrams have been determined for binary mixtures of 4-dodecyloxy-4′-cyanobiphenyl, (12OCB, smectic Ad) and 4-pentyl- or 4-heptyl-4′-isothiocyanatobiphenyl (5BT or 7BT, smectic AE). The S-I, S-N and N-I phase transition enthalpies of these mixtures have been measured. It has been found that the smectic phases are separated by a nematic gap, and that the enthalpies ΔHS E→I and ΔHS E→N rapidly decrease with the increasing proportion of 12OCB.Keywords
