CCH3 shows the formation of dimers related by a centre of symmetry and close contacts of the cyano groups between neighbouring molecules (see Table 5). The molecules are arranged in layers and overlap more or less with the bicyclohexyl units. 

In 1989, Walz et al. [80] reported on the crystal and molecular structures of four mesogenic compounds of the series trans, tran5-4,4 -m-n-dialkyl-(la,l -bicyclohexyl)-4)S-carbonitrile (CCNnm). The chemical structure of the mesogenic CCNnm is presented in Fig. 11.

The next development on water-oil isotherms was presented by Mohwald s group at the Max-Planck Institute in Berlin [21,22]. They investigated monolayers of dipalmitoyl phosphatidylethanolamine (DPPE) at interfaces of water and hydrocarbons -dodecane (C]2, -hexadecane (Cig), and bicyclohexyl (BCH). The transition pressure was increased and the molecular area at transition decreased in the order Cig—C12 BCH. Also the heat of transition was decreased in the same order, and was more strongly decreasing with...
