Abstract
Methods for fabricating a solution-processed OLED are provided. The methods include depositing an organic layer comprising mixture of an organic electron acceptor and an organic electron donor to form a layer that is insoluble to a non-polar solvent. Devices containing the organic layer may demonstrate improved lifetime and have a lower operating voltage while maintaining good luminous efficiency.
