Gold Nanoparticles–Dynamic Constitutional Frameworks as Adaptive Hybrid Conjugates for Enzyme Immobilization

ChemistryEurope, EarlyView.
Dynamic constitutional frameworks (DCFs) and gold nanoparticles (AuNps) assemble into larger and well‐distributed conjugates providing an efficient platform for biosensing and biocatalytic applications. Dynamic constitutional frameworks (DCFs), connecting monomers via reversible covalent bonds, can initiate the assembly of gold nanoparticles (AuNps ...

Redox‐Dependent Luminescence in a Pentavalent Uranyl Complex

ChemistryEurope, EarlyView.
Redox‐dependent luminescence in a molecular pentavalent uranyl complex supported by a pyridine dipyrrolide pincer ligand is presented. Electrochemical and chemical reduction of the uranyl(VI) species provides a stable uranyl(V) complex that emits blue light from a high‐energy excited state. The anti‐Kasha emission is credited to the presence of “nested”
