TL;DR: This Focus Review surveys representative examples of pH-controllable supramolecular systems with interesting features and state-of-the-art applications such as conformational changes within individual molecules; folding/unfolding of polymers; logic function; ON-OFF switchable colorimetric sensing; and regulation of the substrate flow in nanocontainers.

TL;DR: The combination of different inputs involving water, acids, salts and an amine leads to different fluorescence outputs from the dynamic rotaxane, hence, producing a prototype for expressing molecular logic.

TL;DR: A mechanism for the partial disassembly of the two dynamic [2]rotaxanes, involving the cleavage of the kinetically labile imine bonds by water molecules, is proposed.

TL;DR: In this article, a series of 2,6-bis(imino)pyridyl-based V-shaped compounds bearing various para-substituents on the terminal aromatic rings [C5H3N(CHN-C6H4R)2; R = OMe, iPr, Me, H, Cl, F, and CF3] have been prepared and investigated for their reversible binding with the dumbbell-shaped cations NH2+−{CH2−C 6H3(OMe-3,5)2}

TL;DR: The dissociation ofpseudorotaxane DB24C8⊃1-H·PF6 by an excess of TEA/DIPEA base mixture possessed a long and sustained, complete dissociation over 60 days and could be tuned by using different stimuli such as triethylamine/diisopropylethylamine and dimethyl sulfoxide.
