Ligand‐Engineered Metal–Organic Frameworks of 3D Infinite Trinuclear Zinc Units for Photocatalytic Monooxygenation of Sulfenamides

Advanced Science, EarlyView.
The rarely investigated metal–organic frameworks (MOFs) of 3D infinite trinuclear zinc units are designed and synthesized. Through controllable programming of ligands, their Lewis acidity and photoactivity are fine‐tuned to enable these MOFs as promising catalysts for the cycloaddition of CO2 and photocatalytic monooxygenation of sulfenamides and ...
