Near-infrared-II thermally activated delayed fluorescence organic light-emitting diodes†
Abstract
The first thermally activated delayed fluorescence (TADF) emitter and organic light-emitting diodes (OLEDs) in the near-infrared (NIR) II region (λEL,max = 1010 nm) were realized via intermolecular charge-transfer aggregates. This work provides a promising strategy for achieving TADF in the NIR-II region.
