Binary systems between calamitic mesogens exhibiting smectic phases and n-alkane

Abstract

Some binary systems between calamitic mesogens exhibiting SmA, CrB, and CrE phases and n-alkane were investigated. Phase diagrams and temperature dependences of layer spacing of the smectic phases were newly determined in two binary systems of 12TCB/n-dodecane (CrE, SmA) and 8CBAA/n-decane (CrB, SmA) using DSC and X-ray diffraction. The temperature dependences were compared with our previous data for SmA, CrB, and CrE phases. The characteristics of the binary systems were discussed comprehensively.
