The silicon-locked host enables highly efficient blue emission with minimized non-radiative loss.

High-energy blue excitons often lead to material degradation, particularly at the host-guest interface. 124694

The development of silicon-locked phosphine oxide hosts represents a major step forward for blue OLED technology. The dual encapsulation strategy not only improves immediate performance metrics but also addresses the long-term stability issues that have historically hindered the commercial application of high-efficiency blue emitters. The dual encapsulation strategy not only improves immediate

Experimental data confirms that the dual encapsulation method significantly extends the T50cap T sub 50 By utilizing a "dual encapsulation" strategy for electron

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.
