Molecular aggregated morphology of mixed monolayer composed of cyanine dye and fatty acids during compression was investigated on the basis of an atomic force microscopic observation. Optical properties of the monolayers were also evaluated from a reflected spectroscopy. 3,3'-Dioctadecyl-2,2'-oxacyanine perchior ate as dye and palmitic, arachidic, lignoceric monatonic acids as fatty acid were used for monolayer composition. Absorption behavior revealed formation of J-aggregate in the monolayer of cyanine dye and fatty acids. In particular, a specific band structure was observed for (cyanine dye/palmitic acid :50/50) mixed monolayer and also confirmed -that the structure corresponds to J-aggregate. Formation of J-aggregate in the system depended on alkyl chain length of faty acid and composition ratio. For example, mixed system of monatonic acid formed J-aggregate even the case of composition ratio of 25/75 -40/60, although that of palmitic acid formed it only the case of that of 50/50. Also ternary system of the monolayer formed J-aggregate. A required phase separated structure, which functional cyanine dye molecules were confined by fatty acid molecules at a nanometer order in the mixed monolayer cannot be constructed.

基于原子力显微镜观察，研究了由花青染料和脂肪酸组成的混合单层在压缩过程中的分子聚集形态。还通过反射光谱评估了单层的光学性质。将3,3'-双十八烷基-2,2'-氧花青酸作为染料，将棕榈酸、花生酸、木蜡酸作为脂肪酸用于单层组合物。吸收行为揭示了花青染料和脂肪酸单层中 J-聚集体的形成。特别地，观察到(花青染料/棕榈酸：50/50)混合单层的特定能带结构，并且还证实该结构对应于J-聚集体。体系中J-聚集体的形成取决于脂肪酸的烷基链长度和组成比。例如，一元酸的混合体系即使在组成比为25/75-40/60的情况下也形成J-聚集体，而棕榈酸的混合体系仅在50/50的情况下形成J-聚集体。单分子层的三元体系也形成J-聚集体。无法构建所需的相分离结构，其中功能性花青染料分子被脂肪酸分子以纳米级限制在混合单层中。
