Enantio‐ and Diastereoselective Synthesis and Spiral‐Stair‐Like Single Helix Assembly of Figure‐Eight Cyclophenylenes

open access: yesAngewandte Chemie, EarlyView.
We present here the enantio‐ and diastereoselective synthesis of chiral figure‐eight [10]cyclophenylenes via the rhodium‐catalyzed four consecutive intramolecular [2 + 2 + 2] cycloadditions of dodecaynes with two flexible biphenyl units, resulting in increased rotational freedom of the reaction intermediates.

Breaking the Activity‐Stability Trade‐Off of RuO2 via Metallic Ru Bilateral Regulation for Acidic Oxygen Evolution Reaction

open access: yesAngewandte Chemie, EarlyView.
RuO2 electrocatalysts, which followed a kinetically favorable lattice oxygen mechanism, perform a preferable intrinsic activity, but poor stability for acidic oxygen evolution. This work offer a strategy which introduce metallic Ru onto RuO2 to build the Ru4+─O─Ru0 interfacial structure for decreasing the Ru4+ oxidation state and promoting ...

A Hypoxia‐Triggered Bioreduction of Hydrophilic Type I Photosensitizer for Switchable In Vivo Photoacoustic Imaging and High‐Specificity Cancer Phototherapy

open access: yesAngewandte Chemie, EarlyView.
A hydrophilic type I phototherapeutic agent (NanoPcN8O) was developed which selectively responded to hypoxic tumor microenvironments and switched on type I photodynamic and photothermal effects as well as a photoacoustic signal for activatable photoacoustic imaging and tumor phototherapy.
