Ferrocene-containing Side Chain Polyrotaxanes Obtained by Radical Copolymerization of Styrenes with Acrylamide with a [2]Rotaxane Structure

Abstract Radical copolymerization of styrenes and a [2]rotaxane monomer composed of ferrocene-containing N,N-dialkylacrylamide and dibenzo[24]crown-8-ether (DB24C8) yielded side chain polyrotaxanes.

Rotaxanes of a Quaternary Azaaromatic Character

In the paper rotaxanes containing an electron accepting ring are described, they are followed by those having electron donating ring. Syntheses, properties and possible applications of considered species are presented.

Crystal structures of the dinitrate-bis-(acetylenedicarboxylate) and acetylenedicarboxylate pseudorotaxane complexes of [24-pyrimidinium crown 6

The reaction of [24-Pyrim C6][ \( {\text{NO}}_{{\text{3}}} \)]6 · 8H2O with the monopotassium salt of acetylenedicarboxylic acid yielded single crystals of [24-Pyrim C6][C4O4]2[\( {\text{NO}}_{{\text{3}}} \)]2 · 7H2O, (1). The compound crystallized in the triclinic space group P\( \overline{1} \), with a = 9.731(8) A, b = 10.953(9) A, c = 14.270(14) A, α = 108.06(7)°, β = 94.86(7)°, γ = 99.01(7)°, Z = 1, R = 0.0737, R′ = 0.1024, and 3709 independent reflections. The reaction of [24-Pyrim C6]Cl6 with the monopotassium salt of acetylenedicarboxylic acid gives single crystals of the inclusion complex {[24-Pyrim C6][C4O4]2} · [\( {\text{C}}_{{\text{4}}} {\text{O}}_{{\text{4}}} \)]0.92Cl0.17[H2C4O4]0.16 · 10H2O, (2). The compound crystallizes in the triclinic space group P\( \overline{1} \), with a = 13.543(3) A, b = 14.354(8) A, c = 17.484(8) A, α = 74.35(4)°, β = 79.12(3)°, γ = 69.77(3)°, Z = 2, R = 0.0976, R′ = 0.2662, and 5655 independent reflections with. Strength of binding and size of the nitrate and chloride counter ions in the reacting species determines the mode of acetylenedicarboxylate binding to the cation upon crystallization.

Fast Electrochemically Induced Translation of the Ring in a Copper-Complexed [2]Rotaxane: The Biisoquinoline Effect

Auf der Überholspur: Ein molekulares Shuttle wurde synthetisiert, dessen Ring eine chelatisierende 8,8′-Diphenyl-3,3′-biisochinolin-Einheit enthält. Diese Einheit ist sowohl endocyclisch als auch nicht sterisch gehindert (siehe Bild) und bewirkt erstaunlich schnelle Shuttle-Bewegungen des kupferkomplexierten Rings zwischen zwei Stationen im Millisekundenbereich.

Synthesis of disubstituted cucurbit[6]uril and its rotaxane derivative.

Synthesis of diphenyl cucurbit[6]uril (CB[6]) has been achieved via co-oligomerization of diphenyl glycoluril and unsubstituted glycoluril. The unsymmetrically substituted CB[6], Ph(2)CB[6], was further converted to a rotaxane incorporating bis(dinitrophenyl)spermine. [reaction: see text]

Zwitterionic [2]rotaxanes utilising anionic transition metal stoppers

Zwitterionic [2]rotaxanes are formed when anionic [MBr3]− (M = Co(II), Mn(II)) units are used as stoppers for 1,2-bis(pyridinium)ethane/dibenzo-24-crown type axles.
