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

open access: yesSmall, 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 ...

As urbanization increases, wildlife increasingly encounters people. Coyotes Canis latrans and red foxes Vulpes vulpes are two canid species that have readily adapted to urban environments. Citizen science has emerged as a low‐cost method of collecting data on urban‐adapted species that can benefit management agencies but may provide different results ...
