Abstract

The "staining" cluster-crown compound [Ru<sub>6</sub> C(CO)<sub>14</sub> (η<sup>6</sup> -C<sub>6</sub> H<sub>4</sub> C<sub>10</sub> H<sub>20</sub> O<sub>6</sub> )] verifies that the internal walls of mesoporous silica MCM-41 may be selectively functionalized with propylammonium groups (see picture). By the use of high-resolution transmission electron microscopy the presence and position of the cluster and also of the functional groups may be directly determined.
