Harvesting triplet excitons for near-infrared electroluminescence via thermally activated delayed fluorescence channel

You-Jun Yu et al.

Summary: Near-infrared (NIR) emission is widely used in communication, biomedical sensors, and night vision, while organic thermally activated delayed fluorescence (TADF) emitters have attracted attention for their efficient utilization of excitons. However, the development of NIR TADF emitters lags behind RGB TADF emitters in terms of performance improvement.

Unraveling the Mechanism of Near-Infrared Thermally Activated Delayed Fluorescence of TPA-Based Molecules: Effect of Hydrogen Bond Steric Hindrance

Can Leng et al.

Summary: This study reveals that the fluorescence emission spectrum of CAT-1 is primarily induced by hydrogen bond steric hindrance, which inhibits the twist of the configuration of different excited states. The steric hindrance leads to a more distorted plane, less electron delocalization, and a faster reverse intersystem crossing rate, resulting in longer wavelength NIR TADF emission.

Extended ligand conjugation and dinuclearity as a route to efficient platinum-based near-infrared (NIR) triplet emitters and solution-processed NIR-OLEDs

Marsel Z. Shafikov et al.

Summary: Efficient NIR-emitting organic light emitting diodes are rare due to challenges in increasing non-radiative and lower oscillator strengths as the energy of emissive excited states decreases. A dinuclear metal complex with an extended conjugated ligand can mitigate these effects and reduce contamination by visible light, showing improved performance compared to mononuclear complexes.
