Abstract

Bis zu 30mal schneller als bisher gelingt mit dem hier vorgestellten Verfahren der Aufbau von Supergittern, die Chromophore mit nichtlinearen optischen Eigenschaften kovalent verknüpft enthalten und durch hohe Azentrizität, hohes SHG-Ansprechvermögen und Langzeit- sowie Temperaturstabilität gekennzeichnet sind. Rechts ist die im ersten Cyclus erhaltene Schichtstruktur schematisch dargestellt.
