The synthesis of a supramolecular double hydrophilic block copolymer (DHBC) held together by cucurbit[8]uril (CB[8]) ternary complexation and its subsequent self-assembly into micelles is described. This system is responsive to multiple external triggers including temperature, pH and the addition of a competitive guest. The supramolecular block copolymer(More)
A series of bisimidazolium salts were synthesized as novel guests for the macrocyclic host molecule cucurbit[8]uril (CB[8]). These bisimidazolium-CB[8] binary complexes exhibited a unique cage structure with the imidazolium rings acting as lids, leading to a size-dependent binding selectivity by altering the hydrophobic linker between the two imidazolium(More)
Single-tail peptide amphiphiles, have been explored as a new class of biomaterials in many fields including nanotechnology and tissue engineering. A typical peptide amphiphile molecule is linked through a covalent amide bond between a hydrophilic peptide sequence and a hydrophobic lipid of variable length. In an aqueous environment, these peptide(More)
We demonstrate a supramolecular peptide separation approach by the selective immobilization of peptides bearing an N-terminal tryptophan onto a CB[8]-modified gold substrate, followed by electrochemical release. The CB[8]-stabilized heteroternary complexes were characterized by (1)H NMR, ESI-MS, UV/vis, and fluorescence spectroscopy and cyclic voltammetry.(More)
A method to isolate CB[7] from a CB[5]/CB[7] mixture has been successfully developed by incorporating an alkyl-imidazolium ionic liquid guest of the type [C(n)mim]Br which is only capable of binding with CB[7]. This CB[7]-[C(n)mim]Br complex can be removed from the mixture and a subsequent solid state ion metathesis affords pure CB[7]. Moreover, the(More)
Orthogonal control over systems represents an advantage over mono-functional switches as both the nature and order of distinctly different stimuli manifest themselves in a wide array of outcomes. Host-guest complexes with multiple, simultaneously bound guests offer unique opportunities to address a set of 'on' and 'off' states accessible on demand. Here we(More)
The assembly behavior of aryl/alkyl imidazolium ionic liquid salts in aqueous solution has been investigated. These salts undergo self-assembly into one-dimensional stacks via hydrophobic and π-π interactions upon increasing concentration, which led to a substantial increase in the solution viscosity in water. Addition of the macrocyclic host molecules(More)
