研究目的
To design and synthesize naphthyridine-based thermally activated delayed fluorescence (TADF) emitters for highly efficient blue organic light-emitting diodes (OLEDs).
研究成果
The study successfully synthesized two naphthyridine-based TADF emitters, Cz-ND and tBuCz-ND, which exhibited excellent TADF properties and high photoluminescence quantum yields. The fabricated OLED devices achieved high external quantum efficiencies and narrow band gaps, indicating their potential for applications in flat panel displays and solid-state lighting.
