Interlocked molecules: One-pot pentaknot.
Knots are commonly encountered in everyday life, but their significance extends far beyond their obvious practical utility of being able to bind objects together. As well as serving as decorative motifs — most notably in some illuminated manuscripts such as the Book of Kells — the symbolism often associated with some knots’ intricate interwoven structures has seen them used to represent countri...
متن کاملElectrochromic materials using mechanically interlocked molecules.
Recent investigations on the design and synthesis of electrochromic materials based on switchable three-station [2]catenanes are summarized. The reasoning and preliminary experiments behind the design of electrochemically controllable red-green-blue (RGB), donor-acceptor [2]catenanes are presented. A basis for color generation is discussed in which the tetracationic cyclophane, cyclobis(paraqua...
متن کاملTemplate-directed synthesis of multiply mechanically interlocked molecules under thermodynamic control.
The template-directed construction of crown-ether-like macrocycles around secondary dialkylammonium ions (R2NH2+) has been utilized for the expedient (one-pot) and high-yielding synthesis of a diverse range of mechanically interlocked molecules. The clipping together of appropriately designed dialdehyde and diamine compounds around R2NH2+-containing dumbbell-shaped components proceeds through t...
متن کاملInterlocked porphyrin switches.
We describe the synthesis of a series of interlocked structures from porphyrin-glycoluril cage compounds and bis(olefin)-terminated viologens by an olefin-metathesis protocol. The length of the chain connecting the olefin substituents with the viologen has a marked effect on the products of the ring-closure reaction. Long chains give [2]- and [3]catenane structures, whereas short chains give a ...
متن کاملExperimentally-based recommendations of density functionals for predicting properties in mechanically interlocked molecules.
Mechanically interlocked molecules (rotaxanes and catenanes) have already revolutionized molecular electronics and have the promise of a similar impact in other areas of nanotechnology, ranging from nanoactuators to in vivo drug nanocarriers. However, it would be most useful to have quantitative criteria for predicting structures, binding, and excitation energies for use in designing molecules ...
