The “staining” cluster–crown compound [Ru 6 C(CO) 14 ( η 6 ‐C 6 H 4 C 10 H 20 O 6 )] 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.
