Electron-Deficient Confined Space: Synthesis and Recognition Properties of a Covalent Molecular Cage Built upon Naphthalene Diimides and Benzene Triimides The synthesis of neutral-electron-deficient molecular containers is highly challenging. Nonetheless, the presence of π-acidic units within the confined space of a molecular cage should enable strong anion binding through synergistic anion-π interactions. Here, we report the synthesis of a neutral molecular cage containing five electron-deficient units: two benzene triimide units as roof and floor and three naphthalene diimide units as walls. The study of the cage’s conformational isomerism is presented together with the high affinity of the receptor for acetate.

PhD work of the new Dr Daryna Shymon 🧪

Bioinspired Oxidation of Methane in the Confined Spaces of Molecular Cages Non-heme iron, vanadium, and copper complexes bearing hemicryptophane cavities were evaluated in the oxidation of methane in water by hydrogen peroxide. According to 1H nuclear magnetic resonance studies, a hydrophobic hemicryptophane cage accommodates a methane molecule in the proximity of the oxidizing site, leading to an improvement in the efficiency and selectivity for CH3OH and CH3OOH compared to those of the analogous complexes devoid of a hemicryptophane cage. While copper complexes showed low catalytic efficiency, their vanadium and iron counterparts exhibited higher turnover numbers, ≤13.2 and ≤9.2, respectively, providing target primary oxidation products (CH3OH and CH3OOH) as well as over-oxidation products (HCHO and HCOOH). In the case of caged vanadium complexes, the confinement effect was found to improve either the selectivity for CH3OH and CH3OOH (≤15%) or the catalytic efficiency. The confined space of the hydrophobic pocket of iron-based supramolecular complexes plays a significant role in the improvement of both the selectivity (≤27% for CH3OH and CH3OOH) and the turnover number of methane oxidation. These results indicate that the supramolecular approach is a promising strategy for the development of efficient and selective bioinspired catalysts for the mild oxidation of methane to methanol.

Hydrophobic hemicryptophane cages can improve both efficiency and selectivity of the CH4 oxidation by bioinspired complexes, @InorgChem :
