Examination of covalently bound polymeric stationary phases by luminescence spectroscopy

Luminescnce spectroscopy is used to prove silica-gel surfaces derivatized with [3-(3-pyrenyl)propyl]methyldichlorisilane. Evidence of solution pre-polymerizatiln and subsequent derivatization to acceisibl surface silanols is presented. Conformatonal changes of the bound ligands in polar and non-polar solvents indicate a dynamic surface which minimized its surface area in hostile solvents.
