Changing N^C^O to C^N^O Coordination in Cyclometalated Pt(II) and Pd(II) Complexes Modulates Stability and Emission Characteristics: Toward Brighter Versatility

Chemistry – A European Journal, EarlyView.
A new class of cyclometalated metal complexes with pincer luminophores (C^N^O and N^C^O) is reported. They unite high photoluminescence efficiencies in liquid solutions at r.t. with tunable colors across the visible spectrum and convenient synthetic accessibility.

N‐Aryl Acridone Derivatives as Effective Catalysts for Energy Transfer Reactions

Chemistry – A European Journal, EarlyView.
Acridones derivatives have high triplet energy, are simple accessible, and could be used in challenging [2+2] ENT reactions. ABSTRACT Organic photocatalysts capable of promoting high‐energy triplet energy transfer (EnT) remain limited, particularly for demanding [2+2] photocycloaddition reactions.

Photosensitizing Au(I) Catalysis With Coumarins

Chemistry – A European Journal, EarlyView.
A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐
