A supramolecular bottlebrush polymer assembled on the basis of cucurbit[8]uril-encapsulation-enhanced donor–acceptor interaction

In Situ Loading and Delivery of Short Single- and Double-Stranded DNA by Supramolecular Organic Frameworks

“…Diamondoid SOFs are regular porous supramolecular polyelectrolytes co-assembled by tetracationic monomers and CB [8]. 32 With (4-phenyl)pyridinium as the binding subunit through the CB [8] encapsulation-enhanced dimerization binding motif, which has found wide applications in supramolecular self-assembly, [39][40][41][42][43][44][45][46][47][48][49][50] the water-soluble, polycationic frameworks form ordered pores that have a size of approximately 2.2 nm. 32 Previously, we demonstrated their robustness as molecular drug carriers to attain intracellular transport and low cytotoxicity.…”

Multi-mode supermolecular polymerization driven by host–guest interactions

“…Cucurbit[8]uril (CB[8]) can accommodate two guest molecules in its cavity as a significant macrocycle. 11 Scherman et al reported the CB[8]-mediated heteroternary complexation with 1,1′-dimethyl-4,4′-bipyridinium dication (MV) and an uncharged azobenzene derivative to demonstrate the formation of CB[8] supramolecular polymers from guest monomers bearing azobenzene moieties both in solution and in the solid state. 12 Zhang and co-workers reported a series of CB[8]-mediated supramolecular polymers with naphthalene- and anthracene-containing monomers.…”

Supramolecular assembly confined purely organic room temperature phosphorescence and its biological imaging

“…CBs are a class of water-soluble macrocycle compounds with different numbers of glycoluril units linked by methylene bridges that are able to form stable host–guest complexes with positively charged organic or inorganic guests in aqueous solution. 11 a , d ,12 a ,23 The binding constant between CBs and guests is usually much larger than the corresponding value between CDs and guests due to the strong charge–dipole and hydrogen bonding interactions, as well as the hydrophobic/hydrophilic effect. This strong host–guest interaction can protect and immobilize the phosphor guest efficiently to improve their luminescence efficiency and lifetime in water.…”
