Photoreversible switching of the lower critical solution temperature in a photoresponsive host-guest system of pillar[6]arene with triethylene oxide substituents and an azobenzene derivative.

A new water-soluble thermoresponsive pillar[6]arene with triethylene oxide groups was synthesized. The pillar[6]arene showed lower critical solution temperature behavior in aqueous solution. Its clouding point was photoreversibly switched based on a photoresponsive host-guest system. The trans form of an azobenzene guest formed a stable 1:1 complex with the pillar[6]arene. Complexation increase...

DFT Study of Hydrogen Bonding on Calix[8]arene as Nanostructure Compound

An azobenzene bridge was introduced into the lower (or smaller) rim of p-tert-butylcalix[8]arene to form 1,5-singly bridged calix[8]arene derivatives, respectively. Bridged calix[8]arene of conformationally rigid wereisolated. The stability of the two structures of bridged calix[8]arenes have been compared.The study of organicstructure to form nanoporous structures is a well known in chemistry ...

Size Switchable Supramolecular Nanoparticle Based on Azobenzene Derivative within Anionic Pillar[5]arene

A photo/thermal-switchable supramolecular nanoparticles assembly has been constructed based on an inclusion complex between anionic pillar[5]arene 2C-WP5A and azobenzene derivative Azo-py-OMe (G). The novel anionic pillar[5]arene-based host-guest inclusion complexation was investigated by the 1H NMR titration, 2D ROESY and isothermal titration microcalorimetry (ITC) showing high association con...

A γ-ray and dual redox-responsive supramolecular polymer constructed by a selenium containing pillar[5]arene dimer and a neutral guest.

The first γ-radiation responsive linear supramolecular via pillararene-based host-guest recognition polymer was built successfully. What is more, this supramolecular polymer exhibited dual redox responsiveness.

A pillar[5]arene-fused cryptand: from orthogonal self-assembly to supramolecular polymer.

A pillar[5]arene-fused cryptand with two different cavities was synthesized successfully. It was found that the novel tricyclic host could associate with two different guest species in an orthogonal manner. And based on this orthogonal self-assembly of two host-guest interactions, a novel type of supramolecular polymer was constructed easily and conveniently.
