Physiological and Biomechanical Evaluation of a Training Macrocycle in Children Swimmers

Sports, 2019
Physiological responses related to 400-m front crawl performance were examined in a 11-week training macrocycle in children 11.6 ± 1.2 years old. Fourteen girls and twenty-nine boys completed a maximum intensity 400-m test, at the beginning (&Tau ...

Macrocycle-Induced Modulation of Internuclear Interactions in Homobimetallic Complexes

A synthetic route has been developed for a series of 3d homobimetallic complexes of Mn, Fe, Co, Ni, and Cu using three different pyridyldiimine and pyridyldialdimine macrocyclic ligands with ring sizes of 18, 20, and 22 atoms.

Preparation and Properties of RMg(macrocycle)⁺ Cations with Accompanying Anions Derived from Acidic Hydrocarbons or a Hindered Phenol

, 2016
Reactions of an R2Mg compound, a macrocycle, and fluorene (FlH) or indene (InH) can form RMg(macrocycle)+ and Fl- or In-. Some reactions of RMgOAr (Ar = 2,6-di-tert-butylphenyl) and macrocycles form RMg(macrocycle)+RMg(OAr)2-.

Cambiarenes: Single-Step Synthesis and Anion Binding of a Clip- Shaped Macrocycle with a Redox-Active Core [PDF]

, 2019
We report the synthesis of a novel macrocyclic host molecule that forms in a single step from commercially available starting materials. The core of the macrocycle backbone possesses two quinone rings and, thus, is redox-active.

Anthracene‐Based Amido−Amine Cage Receptor for Anion Recognition under Neutral Aqueous Conditions

ChemistryOpen, 2020
A new amido−amine cage receptor, which combines 1,8‐anthracene diacarboxamide subunit and a polyammonium azamacrocycle, is reported. Bearing both the hydrogen bond donor and the acceptor binding sites, the receptor is able to bind phosphate selectively ...

Alkali Metal-Ion Binding by a Model Macrocycle Containing a C-I···N Halogen Bonded Network: A DFT Study of C-I···M⁺ and N···M⁺ Binding Interactions, M⁺ = Li⁺, Na⁺, K⁺, and Rb⁺

Inorganics
The complexation of an alkali metal ion by a model macrocycle is examined using the M05-2X/DGDZVP DFT method. The macrocycle is built by connecting three cyclopenta[b]pyrrole motifs with alternating acetylene and ethylene linkages. Replacing one of the C-

5,15-Bis(4-pentyloxyphenyl)porphyrin

Acta Crystallographica Section E, 2013
In the title compound, C42H42N4O2, the complete molecule is generated by a crystallographic inversion centre. The porphyrin system exhibits a near planar macrocycle conformation with an average deviation from the least-squares plane of the 24 macrocycle ...
