High hopes: can molecular electronics realise its potential?
This critical review focuses attention on the collective behaviour of switchable mechanically interlocked molecules (MIMs)--specifically, bistable rotaxanes and catenanes--which exhibit reset lifetimes between their ON and OFF states ranging from seconds in solution to hours in crossbar devices.
Click chemistry generates privileged CH hydrogen-bonding triazoles: the latest addition to anion supramolecular chemistry.
This tutorial review will focus on the privileged C-H hydrogen bond donor of the 1,2,3-triazole ring systems as elucidated from anion-binding studies with macrocyclic triazolophanes and other receptors.

A reversibly operating nanovalve that can be turned on and off by redox chemistry is demonstrated and traps and releases molecules from a maze of nanoscopic passageways in silica by controlling the operation of redox-activated bistable rotaxane molecules tethered to the openings of nanopores leading out of a nanoscale reservoir.
Can terdentate 2,6-bis(1,2,3-triazol-4-yl)pyridines form stable coordination compounds?
The first structurally characterized examples of the 1,2,3-triazole motif employed in a terdentate ligand display enhanced steric freedom and a facile receptivity towards a reversible aquation in the…
A nanomechanical device based on linear molecular motors
An array of microcantilever beams, coated with a self-assembled monolayer of bistable, redox-controllable rotaxane molecules, undergoes controllable and reversible bending when it is exposed to…
Ground-state equilibrium thermodynamics and switching kinetics of bistable rotaxanes switched in solution, polymer gels, and molecular electronic devices.
The ground-state equilibrium properties of all three bistable rotaxanes were reflective of molecular structure in all environments, providing direct evidence for the control by molecular structure of the electronic properties exhibited by the MSTJs.
Active molecular plasmonics: controlling plasmon resonances with molecular switches.
Experimental observations suggest that the nanoscale movements within surface-bound "molecular machines" can be used as the active components in plasmonic devices.
Molecular-mechanical switch-based solid-state electrochromic devices.
The solid-state application of electrochromic devices is explored by taking advantage of the colorimetric changes that accompany the electrochemically driven switching of certain bistable catenanes and [ 2]rotaxanes by exploring the fundamental properties of these devices.
