Determination Of The Orientational Order Parameters 〈P*2〉, 〈P*4〉 In A Polysilane Lb Film Via Polarization-Dependent Thg

Abstract

We demonstrate resonant third harmonic generation as a powerful tool for analyzing the quasi 2-D molecular orientational order in a Langmuir-Blodgett film of poly(bis-m- butoxyphenylsilane). By recording Maker-fringes at different angles between the polarization of the fundamental beam and the dipping direction, we were able to determine the order parameters 〈P*2〉 and 〈P*4〉 simultaneously. We found 〈P*2〉 = 0.466 ± 0.030 and 〈P*4〉 equal to -0.12 ± 0.10.
