Brewster Angle Microscope and Atomic Force Microscopy Study of Poly 4-(n-Methacyloyl)-Disperse Red 1-Methacrylic Acid Monolayer at the Air/Water Interface and on the Glass Surface

Abstract Derivatives of azobenzene cause photoisomerization when they are illuminated with UV-vis light. We investigated the photoisomerization of azobenzene derivatives for holographic memory. Organic films containing amphiphile azobenzene derivatives can be applied in molecular devices by changing energy of molecular level, refractive index. In order to investigate of photoisomerization of azobenzene derivatives at the air/water interface, azobenzene derivatives having side chain copolymer containing methacrylic acid [poly 4-(n-methacryloyl)-Disperse Red 1-methacrylic acid (pDRIMA)] was synthesized. The film of azobenzene derivative was characterized by the measurements of Brewster Angle Microscope (BAM) images at the air/water interface and Atomic Force Microscopy (AFM) images on the glass substrate.
