英文摘要: We investigated 4-heptyloxy-4'-n-cyanobiphenyl (70CB) Langmuir films by monolayer compression using Maxwell displacement current (MDC) and optical second harmonic generation (SHG) measurements. In the region with a slope in the surface pressure - area (pi-A) isotherm, it was found that the s-s and p-s SH signals were suddenly generated by monolayer compression, although the change of MDC was very gentle. This result reveals the appearance of phase transition accompanying the monolayer structural change from C-infinitynu to Cs-symmetry, due to the shear induced azimuthal in plane reorientation in monolayers.
