Electrostatic field induced patterning: a method for controlling the anisotropy of films of polar organic molecules — •Sven Verpoort¹, Ansgar Draude¹, Rafael Meinhardt¹, Hilmar Franke¹, and Roger A. Lessard² — ¹Fachbereich Physik / Angewandte Physik, Universität Duisburg-Essen, Lotharstr. 1, D-47048 Duisburg, Germany — ²COPL, department de physique, génie physique et optique, Université Laval, Québec, Canada G1K7P4

The presence of electrostatic charges on the surface of electrically isolating substrates like glass or polymers is able to control the orientation of vapor deposited polar organic molecules.

Different methods for the fabrication of charge patterns have been used with inorganic glass: friction, Corona, contact charging, e-beam charging...

Optically anisotropic layers of the azo dye DR1 have been prepared. The anisotropy is detectable by a change in the optical transparency and the pattern reflects the previously recorded charge distribution.
