Detection of the reversible flow behavior of 4-heptyloxy-4'-cyanobiphenyl monolayer at air-water interface by compression and expansion with Maxwell displacement current and optical second harmonic generation

Yamamoto T, Tojima A, Manaka T, Iwamoto M

The flow behavior of 4-heptyloxy-4'-cyanobiphenyl (7OCB) monolayer is studied during compression and expansion by Maxwell displacement current (MDC) and second harmonic generation (SHG) measurement. It is found that in-plane molecular flow induced reorientation of 7OCB monolayer in L-2 and L-2' phases of the monolayer is reversible. It is concluded that the MDC-SHG method is available for exploring the flow behavior of monolayers. (C) 2003 Elsevier B.V. All rights reserved.
