Dielectric polarization phenomena of two-dimensional surface organic monolayer comprised of rod-like polar molecules on a water surface have been investigated. It was experimentally shown that Maxwell displacement current (MDC) measurement technique coupled with optical second harmonic generation (SHG) measurement was effective for the study of surface polarization, i.e., spontaneous polarization...
Using optical second harmonic generation (SHG) and polarized absorption (PA) measurements, the n-th orientational order parameters S n (n=1, 2, 3) of 4′-n-pentyl-4-cyanobiphenyl (5CB) films were determined whilst 5CB molecules were deposited onto silica substrate coated with a trans- or cis-form 6Az10PVA (azobenzene side-chain polymer) monolayer by evaporation method. The experimental results...
