Click'n ROPISA: One‐Pot Synthesis of Ultrabright Fluorescent Nanoparticles Made of Polypeptides

Angewandte Chemie, EarlyView.
Self‐assembly and fluorophore conjugation proceed rapidly in a one‐pot “Click'n ROPISA” process, yielding intensely fluorescent polypeptide nanoparticles with tunable visible emission. High dye loading enables efficient energy transfer and single‐particle visualization, while the straightforward synthesis provides versatile access to bright ...

Activating Triplet Excitons in COFs via Layer‐Bridging Co Single Atoms for Photocatalytic H2O2 Production and Tandem C─N Coupling

Angewandte Chemie, EarlyView.
This work demonstrates a layer‐bridging coordination strategy of Co single atoms in COFs that promotes the formation and utilization of triplet excited states. The introduction of Co single atoms induces pronounced energy‐level splitting and enhanced spin–orbit coupling, facilitating the generation of 1O2 and O2•– for efficient photocatalytic H2O2 ...

Bioorthogonal Tools for Ethanolamine Lipids and Protein Conjugates

Angewandte Chemie, EarlyView.
An alkyne‐tagged ethanolamine analog (AlkEA) enables bioorthogonal, metabolic labeling of endogenous phosphatidylethanolamine (PE) and its protein modifications. AlkEA is incorporated into PE via the Kennedy pathway, allowing CuAAC‐based visualization of PE and affinity capture of PE‐conjugated LC3, ubiquitin, and GPI‐anchored proteins.

A Mechanical Planar Chiral Rotaxane Induces Single‐Handed Helicity in a Twisted Perylene Diimide

Angewandte Chemie, EarlyView.
A mechanical planar chiral rotaxane (Rmp) is used to induce single‐handed helical chirality (M) in a perylene diimide chromophore, resulting in persistent circular dichroism (CD) and circularly polarised luminescence (CPL). ABSTRACT The twisting of chromophores such as perylene diimides (PDIs) into helical structures affords chiroptical properties from

SOLiD‐MaP: A Photoproximity Labeling Platform for Small Molecule Binding Site Mapping on RNA

Angewandte Chemie, EarlyView.
SOLiD‐MaP is a ligand‐directed photoproximity labeling strategy developed for RNA binding‐site analysis. Singlet oxygen‐mediated labeling creates a proximity‐dependent chemical footprint of bound small molecules on RNA. Coupling this chemistry with mutational profiling enables identification of the ligand‐binding region at nucleotide resolution ...
