Synclinic–anticlinic phase transition in tilted organosiloxane liquid crystalsBasis of a presentation given at Materials Discussion No. 4, 11–14 September 2001, …
In this paper, we considered the case of low molecular weight bimesogenic liquid crystals containing a siloxane moiety as the central part of their molecular architecture. For some of these compounds, both ferro-and antiferroelectric mesophases are present. Two distinct smectic structures can develop as a function of temperature, the first one at high temperature corresponding to a synclinic molecular arrangement with elongated molecules, and the ...
