• ][31][32][33][36]. We have recently found that linear oligosilsesquioxanes functionalized with 2-(carboxymethylthio)ethyl side groups (LPSQ-COOH) can adsorb from their solutions and spontaneously form well-ordered and stable, PSAM-type, 2D nanolayers at the surface of muscovite mica, which renders the

• properties of PSAMs made of ladder-like oligosilsesquioxanes LPSQ-COOH/X on chemo-reactive supports (bare and functionalized muscovite mica) have been analysed. The AFM studies showed that linear oligomers adsorb on the surface of mica and form various types of structures, depending both on the morphology of
