Redox‐Active Guanidines

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

A Negatively Curved Pyrene‐Fused Azaacene

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
A pyrene‐fused azaacene derivative is reported in which steric overcrowding caused by eight phenyl substituents induces bending of the aromatic framework rather than twisting. ABSTRACT Non‐planar aromatic hydrocarbons display distorted π‐frameworks that give rise to unique optoelectronic properties.

A Constellation of Fluorescent Biosensors to Illuminate the Galaxy of Protein Kinases

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Protein kinases (PKs) are enzymes that catalyze phosphorylation of protein substrates involved in a wide variety of biological signalling pathways. This review describes the different families and mechanisms of action and regulation of protein kinases, together with the different classes of fluorescent biosensors that have been engineered and ...
