Synthesis and One‐Electron Reduction of Donor‐Acceptor‐Stabilized SiII–EII–SiII Trimetallylenes (E = Ge, Sn, Pb)

open access: yesAngewandte Chemie, EarlyView.
The first isolable trimetallylenes (SiII)2EII (E = Ge, Sn, Pb) with pπ‐type silanylidenyl donors have been synthesized, having donor–acceptor electronic structures that give rise to near‐infrared absorption and enable access to bis(silanylidenyl)‐supported GeI and SnI radical anions upon one‐electron reduction with elemental potassium.

Molecularly Templated Buried Interfaces for Inverted Perovskite Solar Cells

open access: yesAngewandte Chemie, EarlyView.
We demonstrate a molecularly matched buried interface between SAM and perovskite, enhancing adhesion and passivating defects. This optimized interface achieves 26.58% power conversion efficiency and 86.72% fill factor with exceptional operational stability in both large‐area and wide‐bandgap devices, thereby increasing efficiency and prolonging ...

Decouple H2O2 Electrosynthesis From Microenvironmental Decomposition via Atomic Site Density Engineering

open access: yesAngewandte Chemie, EarlyView.
Using defect‐rich Co‐N2O2 single‐atom catalysts as a model system, this work reveals that atomic site density governs the competition between H2O2 electrosynthesis and microenvironmental decomposition during 2e−‐ORR. Optimised site isolation suppresses HPRR and HDR, thereby establishing a site‐density principle to balance H2O2 formation and ...
