| Research Abstract |
In this study, with in mind in molecular memories based on organic monomolecular or LB film, novel Methyl Yellow type azo dyes were molecular-designed by introducing fluoroalkyl groups to achieve the strong and close-packing monolayer formation. Based on the surface pressure-area measurements, it was made clear that the fluoroalkyl group can effectively enhance the monomolecular film formation. Furthermore, fluoroalkylated azo dyes having N-methyl-glycine segment as a hydrophilic group and Gemini structure highly attained both alignment controlling and close-packing in monolayer of azo dyes, and the most suitable chain length of Gemini structure was determined. With respect to Self-Assembled monolayer formation on to Au base, Methyl Yellow derivatives having both fluoroalkyl and terminal SH groups were also developed.
