Improving the efficiency and operational stability of blue organic light-emitting diodes (OLEDs) remains a primary challenge in display and lighting technology. This paper examines a novel host material, a silicon-locked phosphine oxide, designed to enhance the performance of blue OLEDs. By utilizing a "dual encapsulation" strategy for electron transporting materials, the study demonstrates a significant increase in both device longevity and external quantum efficiency.
