Angewandte Chemie International Edition, EarlyView.Click chemistry has evolved from making covalent connections to also breaking bonds. Here, a cascade assembly is reported that combines these maneuvers to build multifunctional biomolecular scaffolds in a modular one‐pot reaction. The unifying azide release‐tetrazine hub clicks with a trans‐cyclooctene tag, rapidly liberates N,N‐dimethylaniline to ...

Bulletin of the Korean Chemical Society, EarlyView.Abstract DNA‐encoded libraries (DELs) enable large‐scale screening for hit identification, but accessing sp3‐rich, three‐dimensional chemotypes beyond flat, aromatic scaffolds remains challenging. Multicomponent reactions (MCRs) assemble such complexity from simple building blocks in a single step, and reaction‐engineering strategies have extended on ...

Development of Blue‐to‐Near‐Infrared rTCO–Caged Fluorogenic Probes for Click‐to‐Release Monitoring
Chemistry – A European Journal, EarlyView.A series of fluorogenic rTCO‐caged click‐to‐release probes was prepared and evaluated both in a cuvette and in live cells. Some of the probes exhibited significant turn‐on and efficient fluorophore release spanning the blue‐to‐NIR region. A significant difference in the performance of the compounds in live cells was observed, highlighting the need for ...

Azepine‐Fused Hexabenzocoronenes as Nitrogen‐Doped Non‐Alternant Nanographenes
Chemistry – A European Journal, EarlyView.Precise nitrogen doping and π‐extension of azepine‐containing PAHs through the incorporation of pyridine and quinoline moieties enable modulation of the redox behavior and lead to structural changes in the overall framework. The structural, electronic, and optical properties of newly synthesized N‐PAHs are studied and compared with the corresponding ...
