Paper Abstract

Polycrystalline layers of organic azo-dyes like DR1 (Disperse Red) have been prepared from the vapor phase. Due to their large electric dipole moment the orientation of the molecules may be changed or controlled by electric fields. Furthermore the capability of an optically induced TRANS-CIS transition allows an optical reorientation. In this study we will report on the optical recording of stable 2D-patterns in as grown and in electrically or optically preoriented films in the thickness range of 200-500nm.
