Abstract
The purpose of this research wants to create L/LB film of an only organic-dye without Arachidic acid (AA). However, if L/LB has no AA, it will not be in a good condition of molecule state. Therefore, membranous molecule condition is regularly controlled by electric field. Only RhodamineB's molecule condition of L film created a set state that touches the hydrophilic group. And The condition was analyzed the π-A curve. Moreover, only Merocyanine created LB film, which controlled to J band condition. Optical absorption strum of the LB film was measured and examined. As a result, it was found from two analyses that both of molecules were controlled by the electric field.
