1	Monolayers of rod-shaped and disc-shaped liquid crystalline compounds at the air-water interface Albrecht, O., Cumming, W., Kreuder, W., Laschewsky, André, Ringsdorf, Helmut January 1986 (has links) Calamitic (rod-shaped) and discotic (disc-shaped) thermotropic liquid crystalline (LC) compounds were spread at the air-water interface, and their ability to form monolayers was studied. The calamitic LCs investigated were found to form monolayers which behave analogously to conventional amphiphiles such as fatty acids. The spreading of the discotic LCs produced monolayers as well, but with a behaviour different from classical amphiphiles. The areas occupied per molecule are too small to allow the contact of all hydrophilic groups with the water surface and the packing of all hydrophobic chains. Various molecular arrangements of the discotics at the water surface to fit the spreading data are discussed. Monolayers liquid crystals discotics Chemistry and allied sciences
