Deep red to near‐infrared thermally activated delayed fluorescence conjugated polymers toward highly efficient solution‐processible deep red and near‐infrared organic light‐emitting diodes

open access: yesFlexMat, EarlyView.
A series of deep red (DR) and near‐infrared (NIR) thermally activated delayed fluorescence conjugated polymers are prepared, their solution‐processible organic light‐emitting diodes exhibit DR emission with maximum external quantum efficiency (EQEmax) of 6.4%, high luminance of 4254 cd m−2 and emission peak at 678 nm, and a NIR device with EQEmax of 2 ...

Flexible plasma‐sintered transparent conducting electrodes fabricated from particle free gold inks

open access: yesFlexMat, EarlyView.
Thin gold electrodes fabricated via particle free metal organic decomposition inks provide a promising alternative to indium tin oxide for flexible devices. Low temperature plasma sintering enables compatibility with polymer substrates while maintaining transparency and sufficient electrical conductivity for optoelectronic applications.
