A Non-sandwiched Macrocyclic Monolanthanide Single-Molecule Magnet: The Key Role of Axiality [PDF]

, 2011
The dynamic behavior of the tetranuclear zinc(II)–dysprosium(III) complex of the hexaimine [3+3] macrocycle (LPr)6− under an external DC field (1500 Oe) indicates that it is a single-molecule magnet (SMM).

Evaluation of Weak Interactions Between the Ring Component and Axle Component in [2]Rotaxanes With 1,3‐Diyne Moiety

Chemistry – A European Journal, EarlyView.
The rotaxane architecture is a powerful tool to probe weak interactions. The interaction between the ring component and the axle components was estimated by quantitative conformational analysis of the rotaxanes by 1H NMR spectroscopy. Theoretical calculations revealed that C─H⋯N interactions and steric effects would be responsible for the preferred ...

Cucurbit[n]uril binding of platinum anticancer complexes [PDF]

, 2005
The encapsulation of cisplatin by cucurbit[7]uril (Q[7]) and multinuclear platinum complexes linked via a 4,4′-dipyrazolylmethane (dpzm) ligand by Q[7] and cucurbit[8]uril (Q[8]) has been studied by NMR spectroscopy and molecular modelling.

Bambus[6]uril as a Novel Macrocyclic Receptor for the Nitrate Anion

Acta Chimica Slovenica, 2013
By using quantum mechanical DFT calculations, the most probable structure of the bambus[6]uril x NO3(-) anionic complex species was derived. In this complex having C3 symmetry, the nitrate anion NO3(-), included in the macrocyclic cavity, is bound by ...

Modulation of Epigenetic Control by Advanced Molecular Tweezers

Chemistry – A European Journal, EarlyView.
Tailored dimeric molecular tweezers recognize the DNA‐binding part of Histone H4 and interrupt the essential histone‐DNA interaction. ABSTRACT This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics.

Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

Chemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Non‐Dilute Synthesis of Macrodiolides and Macrotetrolides Enabled by Confinement Catalysis

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
Confinement catalysis within a hexameric resorcin[4]arene capsule enables macrolactonization under non‐dilute conditions (up to 0.1 M), overcoming the limitations of high‐dilution protocols (0.1–10 mM). This strategy provides direct access to 18–32‐membered macrodiolides and 26–32‐membered macrotetrolides in one pot and unlocks previously inaccessible ...
