Azobenzene‐Functionalized Ionic Liquids: Light‐Responsive Surfactants With Catalytic Potential
ChemistryOpen, Volume 15, Issue 5, May 2026.Surface‐active imidazolium‐based ionic liquids containing an azobenzene group exhibit different micellization properties upon photoisomerization. Applying a sulfonate tag to the azobenzene moiety profoundly affects the physicochemical behavior of both isomers in water.

Rhodium and cobalt catalysts in the heterogeneous hydroformylation of ethene, propene and 1-hexene [PDF]
, 2007 Hydroformylation is an important commercial process for the conversion of alkenes, carbon monoxide and hydrogen into aldehydes to be further used in the production of various chemicals. The industrial processes operate in a homogeneous mode.
