摘要:

A blue-shifted band has been formed in the merocyanine dye -arachidic acid mixed LB films by adding octadecane molecule of various molar mixing ratios. The polarizing UV-visible absorption spectrum measurements revealed that the formation of molecular aggregates is sensitive to the mixing ratio of octadecane as a third component. The surface pressure - area isotherms indicated that a certain amount of octadecane molecule does not exist in the empty space of merocyanine dye even if mixing ratio of octadecane is small.
