MR-TADF Materials

About

Multiple Resonance Thermally Activated Delayed Fluorescence (MR-TADF) represents a breakthrough in light-emitting technology, combining the principles of thermally activated delayed fluorescence (TADF) with an innovative molecular design. This advanced mechanism enables MR-TADF materials to achieve up to 100% internal quantum efficiency (IQE) in OLED applications by efficiently utilizing both singlet (S 1 ) and triplet (T 1 ) excitons. The term "Multiple Resonance (MR)" highlights the unique delocalization of electronic states within the molecule. By strategically positioning electron-deficient and electron-rich atoms in an ortho-configuration within the fused aromatic structure, MR-TADF materials achieve spatial separation of the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO), while maintaining close energetic alignment. This distinctive design ensures: Exceptionally Sharp Emission Spectra Outstanding PLQY Minimal Stokes Shift (< 30 nm) Narrow full width at half maximum (FWHM) Explore our MR-TADF materials, including DABNA-1 and its derivatives, to revolutionize your OLED designs with unmatched efficiency and precision.
