METHOD OF PREPARATION OF ORGANIC OPTOELECTRONIC AND ELECTRONIC DEVICES AND DEVICES THEREBY OBTAINED

摘要

A method for preparing an organic electronic or optoelectronic device is described. The method comprises depositing a layer of fluorinated polymer (103) on a substrate (101, 102), patterning the layer of fluorinated polymer to form a relief pattern and depositing from solution a layer of organic semiconductive or conductive material on the substrate (105, 106). The fluorinated polymer may be a fluorinated photoresist and may be treated by exposure to ultraviolet light and ozone prior to the deposition of the layer of organic semiconductive or conductive material. The method has particular application in the preparation of organic light emitting devices by ink jet printing.
