Chirality‐Driven Piezocatalysis in MOFs: Achieving Efficient Cocatalyst‐Free Hydrogen Evolution

Angewandte Chemie, EarlyView.
We report a chirality‐driven post‐synthetic modification strategy that grafts chiral L‐histidine (L‐His) onto the Hf6 clusters of MOF‐808(Hf), which significantly boosts the piezoelectricity and charge transfer efficiency, thus significantly enhancing the piezocatalytic performance of MOF‐808(Hf).

To Greater Twist: A Kinetically Biased π‐Radical Cascade

Angewandte Chemie, EarlyView.
π‐Radical cascades enable step‐economic construction of complex polycyclic aromatic frameworks. In this work, we show that a multifurcating pathway can be kinetically steered toward a single, more distorted product. This counterintuitive “falling‐upward” outcome arises from an intrinsic mechanistic bias, revealing a broader dimension of control in π ...

Conformationally Switchable Copper(I) Complexes Amplify BODIPY Triplet Photosensitization

Angewandte Chemie, EarlyView.
Coupling a structurally switchable Cu(I) complex to an organic light‐harvesting chromophore boosts photoinduced intersystem crossing via the transient formation of a Cu(II) intermediate. Spectroscopic, physical, computational, and photocatalytic studies support this unique new approach to solar energy upconversion.
