“…During the past decade, increasing attention has been dedicated to the design and elaboration of redox-responsive self-assembled monolayers (SAMs) for various applications. , Previous works have resulted in some elegant examples that incorporate sophisticated receptors on the electrode surfaces. To enhance the interfacial reactivity, several works have resorted to the elaboration of mixed SAMs in order to favor active molecule accessibility via an alkanethiol as a dilutant. , Much more rarely, a few works have been dedicated to the elaboration of mixed SAMs in order to study the intermolecular reactivity between two immobilized units. − …”

“…The fractions containing the thioketone were concentrated under reduced pressure to a small volume. In the meantime, a stirred solution of (9 H ‐thioxanthen‐9‐ylidene)hydrazine (552 mg, 2.44 mmol) in anhydrous THF (30 mL) was treated with MnO 2 (1.06 g, 12.2 mmol) at 0 °C. After 30 min, the suspension was filtered through a short plug of Celite.…”

A series of unprecedented second generation molecular motors featuring a quaternary stereogenic center substituted with a fluorine atom has been synthesized. It is demonstrated that a seemingly benign replacement of the stereogenic hydrogen for a fluorine atom, regarded as a common substituent in pharmacology, resulted in a dramatic change in the energetic profile of thermal helix inversion. The barrier for the thermal helix inversion was found to increase considerably (by 20-30 kJ mol ), presumably due to destabilization of the transition state by increased steric hindrance when the fluorine atom is forced to pass over the lower half of the motor. This results in the activation barrier for the thermal helix inversion to be higher than the barrier for backward thermal E-Z isomerization, impairing the motor function. A fluorine-substituted motor capable of performing unidirectional rotation is successfully prepared when these limitations are considered in the design phase.

Loading of Vesicles into Soft Amphiphilic Nanotubes using Osmosis

The facile assembly of higher-order nanoarchitectures from simple building blocks is demonstrated by the loading of vesicles into soft amphiphilic nanotubes using osmosis.T he nanotubes are constructed from rigid interdigitated bilayers which are capped with vesicles comprising phospholipid-based flexible bilayers.W hen ah yperosmotic gradient is applied to these vesicle-capped nanotubes,t he closed system loses water and the more flexible vesicle bilayer is pulled inwards. This leads to inclusion of vesicles inside the nanotubes without affecting the tube structure,s howing controlled reorganization of the self-assembled multicomponent system upon as imple osmotic stimulus.
