Single-component Dual TADF system
We are also working on achieving white light emission (WLE) through a conformational isomerization approach applied to a single-component organic system. By introducing a novel twisted donor-acceptor molecule, we generate WLE to cover the visible spectrum via simultaneous blue and orange thermally activated delayed fluorescence (TADF). This advancement addresses a longstanding challenge in WLE design in a single-component system and offers a promising avenue for developing highly energy-efficient WLE emitters ideal for WOLEDs. Our findings contribute to a fundamental understanding of TADF mechanisms and hold practical implications for developing advanced lighting and display technologies.
Multicomponent Dual TADF system
Our group currently focuses on developing white organic light emitters (WOLEDs) based on a novel approach utilizing multiple thermally activated delayed fluorescence (TADF) emitters. By combining blue and orange TADF materials without energy-transfer mechanisms, we aim to achieve high-efficiency WOLEDs capable of emitting two or three colors in a single emissive layer. This innovative strategy addresses the limitations of conventional WOLEDs and offers promising opportunities for advancing white organic light emitting diode (WOLED) technology. Our work contributes to the understanding of energy-transfer phenomena but also provides practical implications for the design and fabrication of energy-efficient WOLEDs, paving the way for future advancements in lighting and display technologies.
