Journal ArticleDOI
Post-assembly processing of [2]rotaxanes
Sheng-Hsien Chiu,Stuart J. Rowan,Stuart Cantrill,Stuart Cantrill,J. Fraser Stoddart,Andrew J. P. White,David J. Williams +6 more
TL;DR: The concept of using [2]rotaxanes that carry one or more surrogate stoppers which can subsequently be converted chemically into other structural units, resulting in the formation of new interlocked molecular compounds, is introduced and exemplified.
Journal ArticleDOI
A solid-state switch containing an electrochemically switchable bistable poly[n]rotaxane
Wenyu Zhang,Erica DeIonno,William R. Dichtel,William R. Dichtel,Lei Fang,Ali Trabolsi,John Carl Olsen,Diego Benitez,James R. Heath,J. Fraser Stoddart +9 more
TL;DR: In this article, a threading-followed-by-stoppering approach was used to synthesize bistable main-chain poly[n] rotaxanes for molecular switch tunnel junction devices.
Journal ArticleDOI
Towards a molecular abacus
Mark V. Reddington,Alexandra M. Z. Slawin,Neil Spencer,J. Fraser Stoddart,Cristina Vicent,David J. Williams +5 more
TL;DR: The solid state and solution structures of the 1 : 1 complex formed between the cyclobis(paraquat-p-phenylene) tetracationic cyclophane and 1,5-dimethoxynaphthalene has led to the successful design and characterisation by X-ray crystallography of a prototype for the construction of a molecular abacus as mentioned in this paper.
Journal ArticleDOI
Redox-induced ring shuttling and evidence for folded structures in long and flexible two-station rotaxanes
Tohru Yamamoto,Hsian-Rong Tseng,J. Fraser Stoddart,Vincenzo Balzani,Alberto Credi,Filippo Marchioni,Margherita Venturi +6 more
TL;DR: In this article, two dumbbell-shaped rotaxanes with tetraarylmethane type stoppers, one hydrophobic and another hydrophilic, have been synthesized using template-directed protocols.
Journal ArticleDOI
Powering a Supramolecular Machine with a Photoactive Molecular Triad
Sourav Saha,L. Erik Johansson,Amar H. Flood,Hsian-Rong Tseng,Jeffrey I. Zink,J. Fraser Stoddart +5 more
TL;DR: It is shown, in a wholly artificial system, that aphotocurrent is gated by light, the wavelength of which is specifically tuned to the maximum absorption of the light-absorbingporphyrinchromophoreofamoleculartriad (Fig-ure1a).
