RESUMO
The "staining" cluster-crown compound [Ru6 C(CO)14 (η6 -C6 H4 C10 H20 O6 )] 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.
