Self‐Immolative Gels: Programmable Degradation Using Self‐Immolative Linkers and Polymers

open access: yesChemistry – A European Journal, EarlyView.
Self‐immolative linkers and polymers undergo bond‐cleaving reaction cascades in response to specific stimuli. Their incorporation into gels can be harnessed to release cargo, induce property changes, or trigger degradation in a highly controlled manner. These functions can be employed in applications such as sensing and drug delivery.

Bond and Antibond Resonances: A Unified Framework for Singlet Biradical Character

open access: yesChemistry – A European Journal, EarlyView.
The electronic structure of a variety of singlet biradicaloids may be described in the Lewis picture using single antibonds as the central bonding motif. In conjunction with a consistent set of biradical indicators, we can resolve some long‐standing disputes over the biradical character of molecules such as O3 and S2N2.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

open access: yesChemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.
