Lochmuller, C. H. published the artcileAn examination of chemically modified silica surfaces using fluorescence spectroscopy, Quality Control of 14799-93-0, the publication is Analytica Chimica Acta (1981), 130(1), 31-43, database is CAplus.
Aminated microparticulate silica gel was derivatized with the fluorescent tag, dansyl chloride, to produce a chem.-modified silica surface that could be examined by fluorescence spectroscopy; also a dansylated silica was further derivatized with various alkyl functionalities. The labeled silicas were introduced into solvents and solvent mixtures of different polarities and the emission spectra obtained were compared with the spectra of a model compound, n-propyldansylamide, in the same solvents. Residual amine groups, as well as unreacted silanol groups, produce a polar surface environment reflected in the emission maximum of the spectrum of the modified silica. The degree of residual surface polarity also appears to be a function of the aminopropylsilane reagents used.
