Structural fine-tuning of (-donor-spacer-acceptor-spacer-)n type foldamers. Effect of spacer segment length, temperature, and metal-ion complexation on the folding process

The synthesis of a series of polymers (PDA-nOE) containing an alternating arrangement of electron rich (donor) and electron deficient (acceptor) aromatic units, which are linked by flexible oligo(oxyethylene) (nOE) spacers, is reported. The length of the

Improved synthesis of 1,5-dinaphtho[38]crown-10

We have devised a method of achieving the much-used macrocyclic polyether, 1,5-dinaphtho[38]crown-10, in three steps by a route that is more efficient and requires fewer purification procedures than those reported in the literature to date. The strategy c

Donor–Acceptor [2]- and [3]Catenanes Assembled from Versatile Pre-Organized Cp*Rh/Ir-Directed Pseudorotaxane Tectons

A stepwise self-assembly protocol has been used to synthesize [2]- and [3]catenanes. Firstly, binuclear Cp*Rh/Ir-directed (Cp=pentamethylcyclopentadienyl) pseudorotaxanes were prepared through self-assembly, driven by donor–acceptor interactions between e

Main-chain donor-acceptor polyhydrazone mediated adsorption of an anionic dye from contaminated water

A versatile synthetic approach was applied to synthesize a polyviologen (PV.nBr) polymer via step-growth polymerization of a tetraethylene glycol-linked trinapthyl-based dihydrazide with a bipyridinium-based dialdehyde (BIPY.2Br DA) in water under acidic

Oligocatenanes made to order

The construction of catenanes, comprised of between two and seven interlocked rings, has been achieved. Two tris-1,5-naphtho-57-crown-15 macrocycles template the formation of cyclobis(paraquat-4,4'-biphenylene) to give a [3]catenane, which acts as a templ

Structural and co-conformational effects of alkyne-derived subunits in charged donor-acceptor [2]catenanes

Four donor-acceptor [2]catenanes with cyclobis(paraquat-p-phenylene) (CBPQT4+) as the π-electron-accepting cyclophane and 1,5-dioxynaphthalene (DNP)-containing macrocyclic polyethers as π-electron donor rings have been synthesized under mild co

Enhancement of photoinduced electron-transfer reaction via noncovalent bonding: Cooperative effect of a paraquat molecule and zinc(II)phthalo- cyanine having a macrocyclic ether void

Novel zinc(II)phthalocyanine having a maclocyclic ether void was synthesized. The phthalocyanine interacted with a paraquat molecule at the crown ether void, resulting in the formation of a molecular complex. The fluorescence quenching of the complex was dramatically enhanced because of the intermolecular folding of the paraquat within the crown ether void.

Redox-driven switching in pseudorotaxanes

Two donor-acceptor thread-like compounds incorporating viologen (V 2+) units and 1,5-dihydroxynaphthalene (DNP) stations have been prepared. Their ability to form self-assembled charge-transfer (CT) complexes with cucurbit[8]uril (CB[8]) is evi

A macrocyclic receptor containing two viologen species connected by conjugated terphenyl groups

A macrocyclic receptor molecule containing two viologen species connected by conjugated terphenyl groups has been designed and synthesised. The single-crystal X-ray structure shows that the two viologen residues have a transannular N?N separation of ca. 7

Donor-acceptor oligorotaxanes made to order

Five donor-acceptor oligorotaxanes made up of dumbbells composed of tetraethylene glycol chains, interspersed with three and five 1,5-dioxynaphthalene units, and terminated by 2,6-diisopropylphenoxy stoppers, have been prepared by the threading of discrete numbers of cyclobis(paraquat-p- phenylene) rings, followed by a kinetically controlled stoppering protocol that relies on click chemistry. The well-known copper(I)-catalyzed alkyne-azide cycloaddition between azide functions placed at the ends of the polyether chains and alkyne-bearing stopper precursors was employed during the final kinetically controlled template-directed synthesis of the five oligorotaxanes, which were characterized subsequently by 1HaNMR spectroscopy at low temperature (233aK) in deuterated acetonitrile. The secondary structures, as well as the conformations, of the five oligorotaxanes were unraveled by spectroscopic comparison with the dumbbell and ring components. By focusing attention on the changes in chemical shifts of some key probe protons, obtained from a wide range of low-temperature spectra, a picture emerges of a high degree of folding within the thread protons of the dumbbells of four of the five oligorotaxanesa the fifth oligorotaxane represents a control compound in effecta brought about by a combination of Ci-H···O and π-π stacking interactions between the π-electron-deficient bipyridinium units in the rings and the π-electron-rich 1,5-dioxynaphthalene units and polyether chains in the dumbbells. The secondary structures of a foldamer-like nature have received further support from a solid-state superstructure of a related [3]pseudorotaxane and density functional calculations performed thereon.
