The linking of adamantyl, ferrocenyl-, and cyclodextrin-terminated di- and polydimethylsiloxanes via host–guest interactions is presented. The molecules form complexes and lead to novel supramolecular formations of siloxanes. The noncovalent interactions of the functionalized siloxane blocks can be detected in the 1H nuclear magnetic resonance spectra by a chemical shift of the characteristic guest molecule signals. The derivatives show different morphologies in the scanning electron microscopy images. The red-ox behavior of the ferrocenyl-siloxanes and their complexes with the cyclodextrin-siloxanes are studied by cyclovoltammetry.
