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 ...

Self‐Assembled Nanostructured Microgels with Reconfigurable Morphologies

Small, EarlyView.
This work presents bent‐core amphiphiles that self‐assemble into fibrillar, tubular, and helical nanofiber‐like nanostructures, forming organogels that can be emulsified into water as nanostructured microgels. These droplets preserve internal architectures and, when combined with fluorocarbon oils, yield multicompartment emulsions with dynamically ...

Benzoyl‐Xanthenoxanthenes: Versatile Chromophores for Light‐Engaging Applications

Angewandte Chemie, Volume 138, Issue 7, 9 February 2026.
Oxidatively stable benzoyl‐fused peri‐xanthenoxanthene ribbons with NIR emission were synthesized. Their good spectral overlap enabled cascaded Förster resonance energy transfer (FRET) antennae in a nematic liquid crystal phase, achieving directional energy transfer.

Trans‐reflective color filters with brilliant colors by integrating organic dyes with photonic crystals

Smart Molecules, EarlyView.
A novel trans‐reflective color filter design achieves high color purity, >70% transmittance, and exceptional UV/thermal stability by integrating dye‐doped polysulfone with photonic crystals, enabling advanced dual‐mode displays. Abstract Color filters are essential components for optical modulation.

Advancing Single‐Walled Carbon Nanotubes toward Next‐Generation Electronic Materials: The Critical Roles of Purity and Processability

Small Methods, EarlyView.
Single‐walled carbon nanotubes (SWNTs) are promising for a wide range of applications. In particular, their exceptional electrical conductivity positions them as potential alternatives to traditional metal conductors. This review identifies the key mechanisms governing their conductivity within composites and proposes practical pathways for translating
