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.

根据原子力显微镜观察，研究了由氰染料和脂肪酸组成的混合单层的分子聚集形态。还从反射光谱法评估了单层的光学特性。 3,3'-二甲苯二烷基-2,2'-氧酰基的过度疗法作为染料和棕榈酸，蛛网膜，木质酸猴子酸作为脂肪酸的单层组成。吸收行为揭示了在氰胺染料和脂肪酸的单层中形成J聚集酸盐的形成。特别地，观察到（氰染料/棕榈酸：50/50）混合单层的特定条带结构，并确认 - 结构对应于J-聚集酸盐。系统中J聚集的形成取决于脂肪酸的烷基链长度和组成比。例如，魔术酸的混合系统甚至形成J种群，即使组成比为25/75 -40/60的情况，尽管棕榈酸的形成只有50/50的情况。单层的三元系统也形成了J种群。所需的相分离结构，该结构无法构造混合单层中的脂肪酸分子限制在脂肪酸分子中。
