Pure Hydrocarbon Hosts Enabling Efficient Multi-Resonance TADF Blue-Emitting Organic Light-Emitting Diodes.

Pure hydrocarbon (PHC) materials are a class of highly efficient and stable host materials for organic light-emitting diodes (OLEDs), composed solely of carbon and hydrogen atoms. Despite recent great advancements in PHC research, their applications are still mainly limited to phosphorescent OLEDs (PHOLEDs). Thus, expanding PHC materials into other types of OLEDs is critical for advancing organic electronics.
