SOLUTION PROCESSED METAL ION COMPOUND DOPED ELECTRON TRANSPORT LAYERS AND USES IN ORGANIC ELECTRONICS

摘要

Compositions and methods for forming an electron transporting layer of an electronic device by solution processing, as well as electronic devices comprising solution-processed active layer and solution-processed electron transporting layer. The device can be an OLED. The composition comprises: (i) at least one electron transporting material having a molecular weight of 5,000 g/mol or less; (ii) at least one metal ion compound dopant of the electron transporting material; and (iii) at least one solvent capable of dissolving the electron transporting material and the dopant.
