Created Ex Nihilo: A Near‐Infrared Afterglow Luminescent Framework of Imidazole Derivatives for Bioimaging

Angewandte Chemie, EarlyView.
A series of Ir(III) complexes (Ir‐1‐Ir‐4) based on imidazole derivatives provide a new afterglow luminescence mechanism. The work expands the range of afterglow luminescence frameworks to overcome: (i) a lack of new afterglow scaffolds; (ii) the dependence on initial external light activation; and (iii) aggregation‐caused quenching.

Gold Single‐Atom Catalysts Enable Selective Shuttle Hydrochlorination of Alkynes

Angewandte Chemie International Edition, EarlyView.
Gold single‐atom catalysts on activated carbon enable heterogeneous shuttle hydrochlorination of terminal alkynes to vinyl chlorides with high chemo‐ and stereo‐selectivity thanks to cooperation between Au(I) sites and the support. The catalytic system combines broad substrate compatibility, simplified separation, and recoverability, paving the way for
