Excited‐State Antiaromaticity in Nonbenzenoid Aromatics: Examining the Dynamics of Intramolecular Proton Transfer With a Small Driving Force

Angewandte Chemie, EarlyView.
The excited‐state antiaromaticity of hydroxybenzotropyliums (HBTs) can be tuned through substituent effects to bring the aromatic ‘enol’ (E) and keto (K) tautomers close in energy. This leads to abnormally slow excited‐state proton transfer (on the ns timescale), giving rise to dual fluorescence emission and weak photoacidity.

Perilipin‐2‐Anchored Lipid Droplet‐Targeting Phototheranostics

Angewandte Chemie, EarlyView.
This study reports two NIR theranostic dyes, C‐BDP‐OH and C‐BDP‐OMe. C‐BDP‐OMe targets lipid droplets via a dual‐anchoring mechanism with PLIN2, enabling wash‐free tumor imaging. With 62.6% photothermal conversion efficiency, it achieves tumor ablation by downregulating PLIN2, disrupting LD‐mitochondria crosstalk, and triggering apoptosis and ...

Redirecting Excited‐State Proton Transfer Through Supramolecular Polymerization in Nanoconfinement

Angewandte Chemie, EarlyView.
Supramolecular confinement redirects the excited‐state proton transfer pathway of an amphoteric emitter. In water, the molecule undergoes ESPD, whereas co‐assembly with γ‐cyclodextrin forms nanotubes that template slip‐stacked emitter pairs and enable ESIMPT. Structural and photophysical characterization of the assemblies shows that the preorganization
