Designing Enzymatic Reactivity with an Expanded Palette

open access: yesChemBioChem, Volume 26, Issue 11, June 3, 2025.
Innovation in biocatalysis is rapidly increasingly the diversity of catalytic reactivity that can be mediated by enzymes, addressing a key bottleneck for their widespread adoption in industrial chemical synthesis. A key approach to this is building enzymes with unnatural catalytic components that provide an expanded palette with new possibilities for ...

Molecular Engineering for Enhancing the Dielectric and Optoelectronic Properties of Antimony Corroles

open access: yesSmall Science, Volume 5, Issue 6, June 2025.
Molecular engineering of antimony corroles with various β‐substituents and the ability to modulate the oxidation state of the metal ion is employed to demonstrate exceptional optoelectronic properties. The antimony(V) corrole with SCN substituents shows enhanced charge carrier mobility, a high dielectric constant, and a broad absorption range ...
