Abstract

Official abstract text for this publication.

The present invention relates to the improvement of organic electronic devices, in particular electroluminescent devices, by using compounds which can have a plurality of isomers, where one of these isomers is present in excess.

First claim

Opening claim text (preview).

The invention claimed is: 1. An organic electronic device comprising cathode, anode, and at least one layer, said at least one layer comprising at least one atropisomeric organic compound, wherein said at least one atropisomeric organic compound capable of forming diastereomers has an atropisomeric excess of at least 70%, and wherein said at least one atropisomeric organic compound comprises one or more single bonds having an activation energy for rotation about said one or more si…
