Intrinsically Chiral Excimers: Water‐Compatible Trityl‐Based Nanoparticles as Tailored Dual Emitters of Circularly Polarized Luminescence in the Vis or NIR Regions

Small, EarlyView.
Dual circularly polarized luminescence (CPL) is demonstrated in pioneering metal‐free organic nanoparticles (ONPs) from a brominated trityl radical derivative. CPL activity in the Vis or NIR regions in aqueous environments is achieved by tayloring the content of radical enantiomers in ONPs, thanks to the generation of intrinsically chiral excimers ...
