Poly (p-phenylene vinylene) as Alignment Layers in Liquid Crystal Displays (LCD's) via the Langmuir-Blodgett Technique.

Abstract

Preparation of alignment layers of PPV via the poly (p-xylene-alpha-diethyl sulphonium perfluorononanoate) precursor has demonstrated initial success. However, UV-vis and grazing angle X-ray techniques have shown that the precursor collapses by centrosymmetric multilayer formation at 25 mN/m and 13 deg C. At these conditions, Z-type deposition on hydrophilic glass results in an irregular lamination/delamination process after 3 iterations. IR measurements have shown nearly complete conversion to PPV by thermal elimination. UV measurements, however, were not found to be representative of the proportion of converted to unconverted units. p1
