Unlocking Two‐Photon Chiral Signatures in DNA‐Stabilized Silver Nanoclusters: Two‐Photon Circular Dichroism and Circularly Polarized Luminescence

Advanced Optical Materials, EarlyView.
Chiroptical properties of DNA‐stabilized silver nanocluster (DNA)2​[Ag16​Cl2​]8+ are presented in linear and nonlinear regime. These water‐soluble, NIR‐emitting nanoprobes demonstrate exceptionally high two‐photon circular dichroism and circularly polarized luminescence brightness.

Effect of Host Anisotropy on Phosphorescent Emitter Orientation and Light Outcoupling in OLEDs

Advanced Optical Materials, EarlyView.
The orientation of the emissive transition dipole moment of a cage‐type Iridium complex can be tuned by the anisotropic alignment of the cohost material, which is expressed as the S$S$ parameter of the film. Thus, the external quantum efficiency of OLEDs can be further enhanced to reach values above 30%.
