Half-rotation in a kinetically locked [2]catenane induced by transition metal ion substitution.
نویسندگان
چکیده
We report on a heterocircuit [2]catenane in which a reversible half-rotation of one ring about the other can be induced, and locked in place, by switching the coordination of the interlocked rings between Pd(II) and Co(III).

Half-rotation in a [2]catenane via interconvertible Pd(II) coordination modes.
Reaction of a [2]catenane with Pd(OAc)2 binds both macrocycles to the metal, locking them in position; treatment with PdCl2, however, results in coordination of only one ring, producing a half-turn in the relative orientation of the [2]catenane components in both solution and the solid state.

Homo-metallic metal alkynyl complexes exhibit interesting catenane structures, but their hetero-metallic catenane counterparts are under-developed. In this work, we report rare examples of bimetallic Au–Cu (DtbpC^C ligand; Dtbp 1⁄4 3,5-di-tert-butylphenyl), Au–Ag (BuC^C ligand), and Au–Cu, Au–Ag (C6FluoC^C ligand; C6-Fluo 1⁄4 9,9-dihexyl-9H-fluoren-2-yl) complexes as well as a trimetallic Au–Ag...
متن کاملCytotoxic Effect of \" Glycated Albumin-Transition Metal Ion\" on Rat Hepatocyte Suspension
Background: Combination of glycation and oxidation is associated with diabetes mellitus. The aim of this study was to clarify the effect of glycated proteins in presence of transition metal ions on production of reactive oxygen species (ROS) in rat hepatocyte suspension. Methods: Glycated albumin was prepared by incubation of bovine serum albumin with 100 mM glucose in 0.3 M phosphate buffer a...
متن کاملInvestigation of effect of magnetic ordering on structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) using ab initio method
Structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) were studied for each of three magnetic configurations nonmagnetic, ferromagnetic, and antiferromagnetic by using density functional theory in generalized gradient approximations (GGA) and strong correlation correction (GGA + U). Due to magnetic transition from antiferromagnetic to nonmagnetic phase, an electr...
متن کاملThree-dimensional architectures incorporating stereoregular donor-acceptor stacks.
We report the synthesis of two [2]catenane-containing struts that are composed of a tetracationic cyclophane (TC(4+)) encircling a 1,5-dioxynaphthalene (DNP)-based crown ether, which bears two terphenylene arms. The TC(4+) rings comprise either 1) two bipyridinium (BIPY(2+)) units or 2) a BIPY(2+) and a diazapyrenium (DAP(2+)) unit. These degenerate and nondegenerate catenanes were reacted in t...
