Researchers make OLEDs brighter by tuning their chirality

Presenting their findings in a paper titled ‘Inverting the Handedness of Circularly Polarized Luminescence from Light-Emitting Polymers Using Film Thickness’ published in ACS Nano, the researchers report that blending achiral polymers with chiral small-molecule additives in the new polymer OLEDs chemistry allowed them to control the handedness/sign of the circularly polarized light through absolute stereochemistry. Another interesting finding is that tuning the circularly polarized light output was performed as a function of the active layer thickness, for a fixed optical isomer of the chiral additive.
