. 2005 Aug;
(31):3927-9.
PMID: 16075074
The introduction of a stereogenic center by a stereospecific synthesis into an optically active, donor-acceptor pretzelane, that exhibits helicity as well as fixed chirality, leads to a marked preference for...

PMID: 15998079
Two switchable, palindromically constituted bistable [3]rotaxanes have been designed and synthesized with a pair of mechanically mobile rings encircling a single dumbbell. These designs are reminiscent of a "molecular muscle"...

Vignon S, Jarrosson T, Iijima T, Tseng H, Sanders J, Stoddart J
J Am Chem Soc
. 2004 Aug;
126(32):9884-5.
PMID: 15303838
Two switchable neutral bistable [2]rotaxanes have been synthesized, and their chemically induced mechanical switching has been studied in solution by 1H NMR spectroscopy. One of the rotaxanes was prepared by...

Chemistry
. 2004 May;
10(10):2555-64.
PMID: 15146527
Six different degenerate [2]rotaxanes were synthesized and characterized. The rotaxanes contained either two tetrathiafulvalene (TTF) units or two 1,5-dioxynaphthalene (DNP) ring systems, both of which serve as recognition sites for...

PMID: 15040731
A [2]catenane in which the macrocyclic polyether, bisparaphenylene[34]crown-10, is interlocked with the tetracationic cyclophane, cyclobis(paraquat-p-phenylene), is shown by dynamic (1)H NMR spectroscopy, using (i). neutral and (ii). anionic chiral shift...
