摘要：

Films of a polymerizable fatty acid (10,12-pentacosadiynoic acid) containing diacetylenic groups were investigated by microfluorescence, film balance techniques, and scanning force microscopy. At the air-water interface the fatty acid forms films whose properties can be controlled via the pH of the subphase. We found that under certain conditions a solid-solid transition occurs which results in two phases with different fluorescence properties of the polymer. The structure of these films was investigated by scanning force microscopy. Images at molecular resolution of both monomeric and polymeric films are reported here for the first time. The fatty acids exhibited in both cases long-range positional order with comparable lattice constants.
