GELATION OF ROOM-TEMPERATURE LIQUID-CRYSTALS BY THE ASSOCIATION OF A TRANS-1,2-BIS(AMINO)CYCLOHEXANE DERIVATIVE

Communication: The formation of an anisotropic gel-a member of a new c lass of gel-is described. A structure is proposed for the liquid-cryst alline gel (see also the cover of this issue), which was formed by the gelation of a room-temperature nematic liquid crystal, achieved by th e self-aggregation of low-molecular-weight molecules through hydrogen bonding. It is shown that the mixture studied exists in three states, anisotropic gel, normal gel, and isotropic liquid, all of which are th ermally reversible. Preliminary measurements of the response of the an isotropic gel to electric fields are presented.
