Many biomolecular motors catalyze the hydrolysis of chemical fuels, such as adenosine triphosphate, and use the energy released to direct motion through information ratchet mechanisms. Here we describe chemically-driven artificial rotary and linear molecular motors that operate through a fundamentally different type o…

[reaction: see text] Bright green boradiazaindacene fluorescence is quenched by an oxidative photoinduced electron transfer (PET) from the excited state fluorophore to the bipyridyl unit complexed to metal cations. The closed shell diamagnetic cation Zn(II) is one of the most effective quenchers of fluorescence in thi…

We present an efficient strategy for the preparation of conjugated microporous polymers incorporating pillar[5]arenes (P5-CMPs) with surface areas up to 400 m 2 g –1 via Pd-catalyzed Sonogashira–Hagihara cross-coupling reaction of triflate functionalized pillar[5]arene with 1,4-diethynylbenzene and 4,4′-diethynyl-1,1′…

Two birds with one stone: Covalent attachment of β-cyclodextrin rings (yellow; see figure) to mesoporous silica nanoparticles (MSNs) results in a dual-cargo release system into which differently sized cargos (blue and red spheres) can be loaded and then released in sequence when triggered by two different stimuli. The…

A pH sensitive carrier is obtained by coating a cyclodextrin vesicle with an adamantane-terminated octapeptide through the formation of an inclusion complex. Upon lowering the pH from 7.4 to 5.0, the formation of peptide beta-sheets on the vesicle surface induces a transition of the bilayer from a sphere to a fiber. T…

Mechanical point-chirality in a [2]rotaxane is utilized for asymmetric catalysis. Stable enantiomers of the rotaxane result from a bulky group in the middle of the thread preventing a benzylic amide macrocycle shuttling between different sides of a prochiral center, creating point chirality in the vicinity of a second…

A bistable CB6-based [3]rotaxane with two recognition sites has been prepared very efficiently in a high yield synthesis through CB6 catalyzed 1,3-dipolar cycloaddition; this rotaxane behaves as a reversible molecular switch and exhibits conformational changes caused by the movement of rings under base, acid and heat…

Linking tetrahedral Cu(I) centers with bent, bridging, nonchelating 3,3‘-bipyridine ligands results in the formation of a three-dimensional extended structure. Interestingly, there is sufficient void space within this coordination framework to allow the interpenetration of a second, identical network, as indicated by…
