Outline of Final Research Achievements

In this research, we aimed to quantitatively link between macroscopic dynamic stimulus and one molecular structure change at the air-water interface, and implemented chirality control of one molecule. Firstly, we prepared a Langmuir film of 1,1’-bi-2-naphthol (BINOL) derivative and controlled the open-close movement reversibly by compression and expansion stimuli. The CD spectra shifted corresponding to the change of dihedral angles. Based on the π-A curve, the energy of the conformational change was estimated and formulated. The results were supported by molecular dynamics simulation. We also developed a LB film system of DNA nonostructures.
