Abstract
The present invention is generally directed to a hole transport polymer comprising a polymeric backbone having linked thereto a plurality of substituents comprising fused aromatic ring groups, with the proviso that the polymer does not contain groups selected from triarylamines and carbazole groups. It further relates to devices that are made with the polymer.
