The anion binding affinity of a macrocyclic Rh complex can be allosterically regulated by reaction with a small molecule (an isocyanide), which effects a change in macrocycle size and shape.

Three squaraine [2]catenanes are synthesized and found to have bright, deep-red fluorescence and high chemical stability. The interlocked molecules undergo two large-amplitude dynamic processes, twisting of the squaraine macrocycle and skipping over the partner tetralactam.

Doubly and triply N-confused hexaphyrins revealed quite unique photophysical properties arising from confusion of pyrrole rings in the macrocycle, and the molecular shape when compared with their parent regular hexaphyrin molecules.

We report the synthesis and characterization of a new heptanuclear cadmium cluster complex formed within a Schiff base macrocycle and study its surprising dimerization in the solid-state and solution to form capsules.

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.

The title compound crystallizes as a chloro-form solvate, C(20)H(23)N(3)O(3)S·CHCl(3), with two crystallographically independent units. The independent units have distinctly different inter-action patterns between the aza-crown macrocycle and the chloro-form solvent mol-ecule. In one of them, the chloro-form mol-ecule forms C-H⋯N and Cl⋯H-C hydrogen bonds with the aza-crown macrocycle (as a pro...

An energy-efficient adsorptive molecular sieving strategy is reported using a crystalline trianglimine macrocycle to separate the elusive m -xylene isomer with over 91% purity.

An efficient chemoselective process for the synthesis of 14- and 15-membered triazole-containing macrocycle compounds has been developed through the combination of two multicomponent reactions and an intramolecular Sonogashira cross-coupling reaction.

The Cu(II) complexes of cyclen and two of its heterosubstituted analogues were shown to be efficient oxidative DNA cleavers. The reactivity strongly depends on the heteroatom inserted into the macrocycle (O > S > N).

A protonated Zn(II) complex with a terpyridine-containing pentaamine macrocycle catalyses ATP hydrolysis in the presence of a second metal ion, which acts as cofactor assisting the phosphoryl transfer from ATP to an amine group of the receptor.
