A water-soluble supramolecular polymer constructed by pillar[5]arene-based molecular recognition

A water-soluble linear supramolecular polymer was efficiently constructed driven by pillar[5]arene-based host–guest molecular recognition.

Pillar[5]- and pillar[6]arene-based supramolecular assemblies built by using their cavity-size-dependent host–guest interactions

We discuss various pillar[5]- and pillar[6]arene-based supramolecular assemblies built using their host–guest interactions.

Pillar[5]arene-based diglycolamides for highly efficient separation of americium(iii) and europium(iii)

Pillar[5]arenes were functionalized with ten diglycolamide (DGA) arms on both sides of the pillar framework and were found to exhibit excellent separation and extraction efficiency towards Am(iii) and Eu(iii) at high acidity.

Synthesis of various supramolecular hybrid nanostructures based on pillar[6]arene modified gold nanoparticles/nanorods and their application in pH- and NIR-triggered controlled release

Organic/inorganic supramolecular hybrid micelles, onion-like disks and vesicles were obtained by the self-assembly of water-soluble pillar[6]arene stabilized gold nanoparticles/nanorods with different amounts of a hydrophobic chain functionalized paraquat derivative in water.

Chemical-responsive complexation between a pillar[10]arene with mono(ethylene oxide) substituents and a 2,7-diazapyrenium salt

A novel pillar[10]arene with twenty mono(ethylene oxide) substituents was synthesized and its chemical-responsive binding to a 2,7-diazapyrenium salt was studied.

Novel binding regioselectivity in the interpenetration of a non-symmetric axle into a non-symmetric pillar[5]arene wheel

A non-symmetric pillar[5]arene bearing methyl and pentyl rims can regioselectively bind 5-bromovaleronitrile, with the directionality of CN@methyl rim and Br@pentyl rim.

A low pH sensor from an esterified pillar[5]arene

An esterified pillar[5]arene, incorporated into a PVC membrane, displays a non-Nernstian response to changes in pH.

An enzyme-responsive supra-amphiphile constructed by pillar[5]arene/acetylcholine molecular recognition

A novel molecular recognition motif between a water-soluble pillar[5]arene (WP5) and acetylcholine is established with an association constant of (5.05 ± 0.13) × 10⁴ M⁻¹.
