Dual Porphyrin Sensitized Photocatalytic System for Visible‐Light‐Driven CO 2 Reduction

Dye‐sensitized photocatalysis offers a powerful strategy for combining the molecular selectivity of transition‐metal catalysts with the robustness and charge‐separation capabilities of semiconductor materials. Herein, we report a dual porphyrin–sensitized TiO 2 platform for visib...

Ligand‐Dependent Locally Excited and Charge‐Transfer Emission in Linear Copper(I) Mesoionic Carbene Luminophores

ABSTRACT We describe the synthesis of a family of photoemissive linear Cu(I) complexes bearing mesoionic carbenes (MIC) and amido ligands of the general formula Cu(MIC)NR 2 (NR 2 = carbazolide, diphenylamide). Careful tuning of the electronic and structural properties of both lig...

Breast cancer metabolism and responsiveness to dichloroacetate: relationships with 15N and 13C natural abundance

Abstract Background Metabolic reprogramming is a hallmark of breast cancer (BrCa), with alterations in glycolysis, glutamine metabolism, and the urea cycle contributing to tumour progression. Dichloroacetate (DCA), a pyruvate dehydrogenase kinase (PDK) inhibitor, shifts metabolis...

Enhancing Electrochemiluminescence with Two-ComponentSpontaneously Adsorbed Monolayers and Films

Abstract Multicomponent films offer important opportunities in electrochemiluminescence, ECL, including the possibility to coimmobilize an electron transfer mediator to facilitate the generation of radicals from a coreactant and to enhance indirect ECL at potentials that are lowe...
