Synthesis of nanoscale carceplexes from deep-cavity cavitands.
نویسندگان
چکیده
Deep-cavity cavitands were shown to undergo carceplex reactions in which two cavitand tetrols were covalently linked using bromochloromethane; the efficiency of the "dimerization" was closely tied to the templating guest molecule incarcerated within the host.

Halogen bonded analogues of deep cavity cavitands.
The first examples of halogen bonded analogues of deep cavity cavitands with guest binding properties, formed between N-alkyl ammonium resorcinarene halides as acceptors and bromotrichloromethane as the donor, are reported in the solid state and in solution.
متن کاملDeep cavitands featuring functional acetal-based walls.
The synthesis of deep cavitands with functionalized acetals as a fourth-wall is described. Recognition properties and stabilities of the complexes of two representative cavitands with aliphatic, aromatic, carbocyclic and adamantane guests were evaluated by NMR methods.
متن کاملGuest-controlled self-sorting in assemblies driven by the hydrophobic effect.
The extent of self-sorting in systems comprised of two different deep-cavity cavitands is investigated. The nature of the guest(s) encapsulated in the resulting assemblies is shown to profoundly influence the extent of self-sorting.
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 کاملSelf-assembled capsules based on tetrafunctionalized calix[4]resorcinarene cavitands.
Calix[4]resorcinarene-based cavitands with a bowl-shaped aromatic cavity are widely used as scaffolds for covalently bound and self-assembled capsules. There are two main categories of calix[4]resorcinarene-based cavitands that are tetrafunctionalized at the upper (wider) rim: one category includes derivatives that have functionalized bridges between pairs of hydroxy groups of the calix[4]resor...
