A novel tri-pillar[5]arene based supramolecular polymer (JP5G) shows multiple stimuli-response properties and could detect and remove Hg2+ from aqueous solution.
The series of gemini amine-oxide surfactants with the formula CnH2n+1CONH(CH2)2N+O–(CH3)–(CH2)3–(CH3)N+O– (CH2)2NHCOCnH2n+1 (n = 11, 13, 15, and 17) have been synthesized, and their pH-stimuli responsive behavior in aqueous solution has been studied.
Abstract
Redox-stimulated host–guest chemistry was applied for the electrochemical Peltier effect, which is a heat transportation phenomenon observed in redox-active electrolytes. The refrigeration capability was enhanced up to 70%. By the addition of alpha-Cyclodextrin (α-CD) into I−/I3− aqueous solution, the amount of heat transported from the cathode side to the anode side was observed. The enhancement of the heat transportation was derived from the elimination heat of I3− from α-CD associated with the shift of host–guest equilibrium caused by the exhausting of I3− by the reduction. This is the first report that utilized the stimuli-responsive supramolecular interaction for heat transportation.
The successful self-assembly of a stimuli-responsive aqueous supramolecular hyperbranched polymer from small molecules and the macrocyclic host cucurbit[8]uril (CB[8]) is reported. This self-healing supramolecular network can act as a soft matter barrier at liquid–liquid interfaces.
Stimuli-responsive luminescent supramolecular polymers were synthesized via hydrogen bonding, which could be further used to build controllable, rewritable paper.
Stimuli-responsive amphiphilic Janus mesoporous nanosheets with pH-triggered emulsification performance, switchable catalytic activity in aqueous solution and oil-phase-type-dependent catalytic activity at an emulsion interface were crafted.
A novel pseudorotaxanes-type crosslinker of a supramolecular polymer network (WP5-PN) was constructed based on water-soluble pillar[5]arene (WP5) and naphthalene dimethylamine derivative (PN) via host-guest interactions.
