Outline of Final Research Achievements

Molecules have random orientations in 3D solutions. On the other hand, molecules can align at the 2D air-water interface depending on their polarity. Using this character of the molecule, conformation of molecule can be tuned by external lateral force. In this work, the motion of these molecules at the air water interface was analyzed. Here amphiphilic fluorescent molecules were used, which show strong fluorescence by inhibition of internal molecular rotation.
