Bright Tin Halide Perovskite Quantum Dots via Organic Dication Compensatory Doping

open access: yesAngewandte Chemie International Edition, EarlyView.
Tin halide perovskites (THPs) are attractive near‐infrared emitters. Confined THP quantum dots (QDs), however, show low emissivity and valence intraband transitions due to self‐p‐doping. We present aliovalent substitution of cesium with organic dications as a compensation strategy to upshift the Fermi level.

An Alkali Amide Approach to Triphosphabenzenes

open access: yesAngewandte Chemie International Edition, EarlyView.
Alkali metal amides offer a simple route to phosphorus aromatics. LiNMe2 catalyzes [2+2+2] cyclotrimerization of a phosphaalkyne, while tetrahydrofuran (THF) stabilizes a λ4‐triphosphabenzene anion intermediate. Using KN(SiMe3)2 switches reactivity to arene C(sp3)─H activation, giving benzylated λ4‐triphosphabenzenes and rare λ5‐triphosphabenzenes ...

The Manifestation of the Electrochemical Potential Gradient in the Kinetic Landscapes of Interfacial Electrochemistry

open access: yesAngewandte Chemie International Edition, EarlyView.
The overpotential constitutes an electrochemical potential difference at the solid–liquid interface, which can manifest itself in different ways. In general, it can not only drive the reaction along the reaction coordinate, but also modulate chemical potentials in the extended environment that shape activation barriers, without necessarily being a ...
