Crystallization-induced phosphorescence of benzils at room temperature

, 2013
Efficient room temperature phosphorescence (RTP) is rarely observed in pure organic luminogens. However, we have newly observed that benzil and its derivatives are nonluminescent in solvents and thin layer chromatography (TLC) plates, but become highly ...

Uncaging Iridium(III) Complexes for Combined Photodynamic and Photoactivated Chemotherapy

Angewandte Chemie International Edition, EarlyView.
Light‐activatable iridium(III) anticancer prodrugs demonstrate how chalcogen coordination controls photoinduced therapeutic activity. Upon visible‐light irradiation, sulfur‐ and selenium‐based caging ligands undergo distinct oxygen‐dependent photoreactions that trigger ligand release and singlet oxygen generation, enabling combined photoactivated ...

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‐
