This paper describes the synthesis of supramolecular polymer brushes via surface-initiated polymerization from adamantane-functionalized initiators that are noncovalently bound to β-cyclodextrin- or cucurbit[7]uril-modified substrates. Surface-initiated atom transfer radical in aqueous media allowed growth various hydrophilic with film thicknesses up 40 nm β-cyclodextrin functionalized surfaces. The adamantane moiety not only forms a host–guest complex β-cyclodextrin, but also cucurbit[7]uril, which provides opportunities study effect binding strength these motifs on thickness and grafting density resulting brushes. Comparison grown cucurbit[7]uril-based noncovalent reveals differences much smaller than expected based solution constant corresponding complexes.
