Cu(II) assisted self-sorting towards pseudorotaxane formation.
نویسندگان
چکیده
A new triamino macrocycle shows Cu(II) templated self-sorting of a pseudorotaxane out of sixteen such possibilities from the mixture of nine components of a tridentate, four bidentate ligands and four transition metal ions.

Water assisted formation of a pseudorotaxane and its dimer based on a supramolecular cryptand.
Water acts as a "molecular clip" to form a supramolecular cryptand structure that improves complexation of a diammonium salt by pseudorotaxane formation, and leads to a novel dimer in the solid state.
متن کاملSelf-assembly of [2]rotaxane exploiting reversible Pt(II)- pyridine coordinate bonds.
A dinuclear self-assembled cationic macrocycle based on Pt(II)-N(pyridine) coordinative bonds and having competitive triflate anions, as metal counterions, is used in the construction of [2]rotaxane and [2]pseudorotaxane architectures assisted by hydrogen bonding. The kinetic lability of the Pt(II)-N(pyridine) coordinative bond controls the dynamics of the [2]rotaxane.
متن کاملDevelopment of ultrasound-assisted emulsification microextraction for the determination of trace zinc and copper by flame atomic absorption spectrometry
In this work, we developed a method based on ultrasound-assisted emulsification microextraction (USAEME) for the determination of zinc and copper by flame atomic absorption spectrometry (FAAS). The method is based on the use of the organic solvent carbon tetrachloride (CCl4) as an extraction solvent. In order to obtain a high enrichment factor, the effect of different parameters affecting the c...
متن کاملA responsive supramolecular metallogel constructed by coordination-driven self-assembly of a crown ether-based [3]pseudorotaxane and a diplatinum(II) acceptor.
Herein, a stimuli-responsive supramolecular metallogel was prepared by orthogonal coordination-driven self-assembly of a crown ether-based [3]pseudorotaxane and a 180° organic di-Pt(II) acceptor.

PAPER Michael Schmittel et al. Reversible cargo shipping between orthogonal stations of a nanoscaff old upon redox input The sterically shielded terpyridine 5 was prepared, both as a new ligand and as part of the four-station nanoscaffold 2. Mixing of terpyridine 5, the parent phenanthroline 4 and the shielded phenanthroline 3 in the presence of Zn 2+ (1 : 1 : 1 : 1) furnished quantitatively th...
