Controlling and Imaging the Functional-Group Distribution on Mesoporous Silica

In, out, shake it all about: The distribution of fluorescence‐labeled amino groups on mesoporous silica was imaged by confocal laser scanning microscopy. The mobility of the aminosilane precursor determines the degree of external vs. pore‐surface functionalization. This observation was used to devel...

Zusammenfassung:In, out, shake it all about: The distribution of fluorescence‐labeled amino groups on mesoporous silica was imaged by confocal laser scanning microscopy. The mobility of the aminosilane precursor determines the degree of external vs. pore‐surface functionalization. This observation was used to develop a simple and general method for the modification of external mesoporous silica surfaces.
