Five-state molecular switching of a [3]rotaxane in response to weak and strong acid and base stimuli.
نویسندگان
چکیده
This communication describes the base- and acid-induced five-state translational isomerization of a [3]rotaxane containing two pairs of N-arylamine and N-alkylamine centers as binding sites for two dibenzo[24]crown-8 components. Gradual molecular shuttling of this [3]rotaxane is achieved in response to both the amount and strength of the added acid or base.

Reversible Mechanical Switching of Magnetic Interactions in a Molecular Shuttle
An acid-base switchable molecular shuttle based on a [2]rotaxane, incorporating stable radical units in both the ring and dumbbell components, is reported. The [2]rotaxane comprises a dibenzo[24]crown-8 ring (DB24C8) interlocked with a dumbbell component that possesses a dialkylammonium (NH2 (+)) and a 4,4'-bipyridinium (BPY(2+)) recognition site. Deprotonation of the rotaxane NH2 (+) centers e...
متن کاملMolecular switch based on a cucurbit[6]uril containing bistable [3]rotaxane.
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 stimuli from one location to the other.
متن کاملThree-state molecular shuttles operated using acid/base stimuli with distinct outputs.
This paper describes the acid/base-mediated three-state translational isomerization of two [2]rotaxanes, each containing N-alkylaniline and N,N-dialkylamine centers as binding sites for threaded dibenzo[24]crown-8 units. Under neutral conditions, the dialkylamine unit predominantly recognized the crown ether component through cooperative binding of a proton; when both amino units were protonate...
متن کاملA finite elements study on the role of primary cilia in sensing mechanical stimuli to cells by calculating their response to the fluid flow
The primary cilium which is an organelle in nearly every cell in the vertebrate body extends out of the cell surface like an antenna and is known as cell sensor of mechanical and chemical stimuli. In previous numerical simulations, researchers modeled this organelle as a cantilevered beam attached to the cell surface. In the present study, however, we present a novel model that accommodates for...
متن کاملNovel Schiff Bases of Pyrrole: Synthesis, Experimental and Theoretical Characterizations, Fluorescent Properties and Molecular Docking
Some new Schiff-base compounds based on pyrrole were synthesized by the reaction of 2-amino-1-methyl-4,5-diphenyl-1H-pyrrole-3-carbonitrile (1)with aromatic aldehydes (2a-2e) in ethanol/acetic acid at room temperature. The structures of the Schiff bases were characterized by full spectral data. The fluorescence emission intensity of the Schiff bases has bee...
