High-energy blue excitons often lead to material degradation, particularly at the host-guest interface.

This approach involves trapping electron-transporting molecules within the host matrix to minimize exciton quenching and reduce the efficiency roll-off at high luminance. 124694

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. a silicon-locked phosphine oxide
