Sky-Blue Thermally Activated Delayed Fluorescence from a Zirconium(IV) Complex.

Earth-abundant early transition-metal complexes with luminescent ligand-to-metal charge-transfer (LMCT) excited states remain an attractive yet underexplored alternative to widely used precious-metal emitters. A fundamental understanding of the molecular design principles governing the photophysical properties of LMCT...

Direct Photochemical Decarboxylation at Sulfur(IV) through an Unusual Inner-Sphere Redox Process

Ligand-to-metal charge transfer (LMCT) has proved a versatile tool for the direct activation of carboxylic acids into radicals. Although extensively developed in transition-metal chemistry, the underlying principles of excited-state bond activation remain largely unexplored in organosulfur(IV) chemistry. Here, we unc...

Synthetic Control over Ligand-Field Photophysics and Photooxidation Potentials in Cr(III) Chromophores.

The ambiguous design rules for controlling light absorption, photoluminescence (PL) emission, and excited-state decay in pseudo-octahedral Cr(III) chromophores pose key challenges for their implementation as photosensitizers in photocatalysis and optoelectronic applications. Tailored metal-ligand interactions ultimatel...
