Supramolecular motifs in dynamic covalent PEG-hemiaminal organogels
Dynamic covalent materials are stable materials that possess reversible behaviour triggered by stimuli such as light, redox conditions or temperature; whereas supramolecular crosslinks depend on the equilibrium constant and relative concentrations of crosslinks as a function of temperature. The combination of these two reversible chemistries can allow access to materials with unique properties....
متن کاملHigh-definition self-assemblies driven by the hydrophobic effect: synthesis and properties of a supramolecular nanocapsule.
High definition self-assemblies, those that possess order at the molecular level, are most commonly made from subunits possessing metals and metal coordination sites, or groups capable of partaking in hydrogen bonding. In other words, enthalpy is the driving force behind the free energy of assembly. The hydrophobic effect engenders the possibility of (nominally) relying not on enthalpy but entr...
متن کاملExtended covalent containers: synthesis and guest encapsulation.
The synthesis and characterization of two new covalent capsules are described. The structures use biphenyl and azobenzene spacers capped on both ends with deep cavitands. The tubular capsules are robust in a range of media and accommodate guests as long as squalene.
متن کاملGuest exchange in an encapsulation complex: a supramolecular substitution reaction.
Encapsulation complexes are reversibly formed assemblies in which small molecule guests are completely surrounded by large molecule hosts. The assemblies are held together by weak intermolecular forces and are dynamic: they form and dissipate on time scales ranging from milliseconds to days-long enough for many interactions, even reactions, to take place within them. Little information is avail...
متن کاملModulation of protein dimerization by a supramolecular host-guest system.
Two sets of cyan and yellow fluorescent proteins, monomeric analogues, and analogues with a weak affinity for dimerization were functionalized with supramolecular host-guest molecules by expressed protein ligation. The host-guest elements induce selective assembly of the monomeric variants into a supramolecular heterodimer. For the second set of analogues, the supramolecular host-guest system a...
