Abstract
Four different types of hetero-structured multilayers of tricosa-2,4-diynoic acid (18-0ADA) and arachidic acid (C20CA) in cadmium salts were prepared, and the structures and polymerization behavior of 18-0ADA in such hetero-multilayers were compared with those in the multilayers of pure 18-0ADA. A new phase of 18-0ADA was found in the multilayers having hydrophilic interactions with C20CA, whereas in the multilayers having hydrophilic interactions by themselves new and original phases were mixed up. To clarify these phenomena, the structures of the same types of hetero-multilayers of fatty acids were also investigated, and no new phases were found for the fatty acids. From these results, it was concluded that large differences in surface area per molecule of two components must be important for the new phase formation in hetero-multilayers.
