Abstract
Raman Microscopy
The resonance structure of 4-nitrophenol undergoes a distinct change upon interaction with surface-modified porous silica, as revealed by Raman microscopy. The silica surface is functionalized with a complex mixture comprising covalently attached acetylated mannoside via a linker, precipitated N-acylurea, and urea. The quinone-type resonance form can be monitored in situ without the need for alkaline treatment. More details can be found in the Research Article by Osamu Kanie and co-workers (DOI: 10.1002/adsr.202500093).
