Journal ArticleDOI
Thermodynamic Synthesis of Rotaxanes by Imine Exchange
TL;DR: These dynamic [2]rotaxanes, which exhibit reversible supramolecular-like behavior in the presence of appropriate catalysts, can be “fixed” by reduction of their imine bonds.
Journal ArticleDOI
Heterosupramolecular Chemistry: Recognition Initiated and Inhibited Silver Nanocrystal Aggregation by Pseudorotaxane Assembly
Declan Ryan,S. Nagaraja Rao,Håkan Rensmo,Donald Fitzmaurice,Jon A. Preece,Sabine Wenger,J. Fraser Stoddart,Nelsi Zaccheroni +7 more
TL;DR: Using dynamic light scattering and nuclear magnetic resonance, it was shown that addition of bis-dibenzylammonium dication initiates aggregation of the silver nanocrystal dispersion by pseudorotaxane assembly.
Journal ArticleDOI
Rotaxanes and Catenanes by Click Chemistry
Ognjen Š. Miljanić,William R. Dichtel,William R. Dichtel,Ivan Aprahamian,Rosemary D. Rohde,Heather D. Agnew,James R. Heath,J. Fraser Stoddart +7 more
TL;DR: The crystal structure of a donor/acceptor catenane formed using the CuAAC reaction indicates that any secondary [p ··· p] interactions between the 1,2,3-triazole ring and the bipyridinium p-acceptor are certainly not destabilizing.
Journal ArticleDOI
An Electrochromic Tristable Molecular Switch.
Junling Sun,Yilei Wu,Yuping Wang,Zhichang Liu,Chuyang Cheng,Karel J. Hartlieb,Michael R. Wasielewski,J. Fraser Stoddart +7 more
TL;DR: A tristable [2]catenane, composed of a macrocyclic polyether incorporating 1,5-dioxynaphthalene (DNP) and tetrathiafulvalene (TTF) units along with a 4,4'-bipyridinium (BIPY(•+)) radical cation as three very different potential recognition sites, interlocked mechanically with the tetracationic cyclophane.
Journal ArticleDOI
Large oligosaccharide-based glycodendrimers.
TL;DR: In this paper, a carbohydrate-based dendritic structure composed of 21 and 27 monosaccharide residues was synthesized in a convergent manner from trisaccharides building blocks.
