Light and cucurbit[7]uril complexation dual-responsiveness of a cyanostilbene-based self-assembled system.

چکیده
A cyanostilbene-based amphiphile (CS) was synthesized, which could self-assemble into non-emissive bilayer vesicles and ultra-thin ribbons. Cucurbit[7]uril (CB[7]) could form an inclusion complex with CS with a significant hypochrome effect, giving a strong blue emission from non-emissive species. CS underwent photoisomerization induced by light irradiation, which allowed the membrane contraction into smaller vesicles.

Dual-responsive supramolecular colloidal microcapsules from cucurbit[8]uril molecular recognition in microfluidic droplets†
The macrocyclic host, cucurbit[8]uril, is used to facilitate cross-linking of colloidal particles and polymers in microdroplets resulting in thermoand photo-responsive supramolecular colloidal microcapsules. Methyl viologen-bearing colloidal particles were prepared using template polymerisation and combined with cucurbit[8]uril and an azobenzene-functionalised polymer within microfluidic drople...

Hydrophobic monofunctionalized cucurbit[7]uril derivatives (1 and 2) were synthesized by clicking CB[7]-azide with propargylated alkylamines. Compounds 1 and 2 form self-inclusion complexes that are transformed into vesicle-type assemblies by addition of guests (3-5) as confirmed by (1)H and DOSY NMR, SEM, TEM, and fluorescence spectroscopy.
متن کاملCucurbit[8]uril-mediated supramolecular photoswitching for self-preservation of mesoporous silica nanoparticle delivery system.
In this study, a novel UV-responsive drug carrier based on mesoporous silica nanoparticles (MSNs) has been designed. A 'self' peptide was introduced onto the MSN surface through a supramolecular photoswitchable heteroternary complexation of cucurbit[8]uril, azobenzene and 4,4'-dipyridyl derivative. The light-induced isomerization of azobenzene contributed to the formation of intelligent cucurbi...
متن کاملAssessment of Cooperativity in Ternary Peptide‐Cucurbit[8]uril Complexes
Evaluating cooperativity for cucurbit[8]uril (CB[8])-mediated ternary complexation is required for understanding and advancing designs of such ternary self-assembled systems. A key issue is to dissect the contributions of the binding steps of the first and second guest molecules to the overall ternary complex formation energy. This is addressed by performing concentration-dependent titrations b...
