A one-pot synthesis of bis-pillar[5]arene was carried out.
The spatial structure of the synthesized bis-pillar[5]arene was confirmed by 2D NOESY NMR spectroscopy data. In methanol, bis-pillar[5]arene (at 1·10–6 M) formed stable nanostructured associates with an average hydrodynamic diameter of 136 nm. Received: 23.11.23. Revised: 28.11.23. Accepted: 28.11.23. Available online: 06.12.23. Recently, materials obtained using supramolecular chemistry approaches, and, in particular, spatially preorganized macrocyclic compounds, have attracted close attention of the researchers. Pillar[n]arenes are of special interest due to their tubular spatial structure and macrocyclic cavity. A similar tubular structure is retained in the supramolecular packaging of pillar[5]arene crystals, forming pores. In this study, we developed a block synthetic approach for the preparation of bis-pillar[5]arene containing amide groups. The ability of the synthesized bis-pillar[5]arene to form stable self-associates in solvents of different polarity (CHCl3 and CH3OH) was demonstrated by the DLS method. In trichloromethane at concentration of 1·10–3 M, monodisperse associates with average hydrodynamic diameter of 227 nm (PDI = 0.28) are formed; in methanol, stable associates (1·10–6 M) have an average hydrodynamic diameter of 136 nm (PDI = 0.21). The results obtained can be used to create new supramolecular systems, molecular machines, or capture and detect various organic molecules. The work was supported by the Russian Science Foundation (Grant No. 22-13-00070, https://rscf.ru/project/22-13-00070/). Investigation of spatial structure of the compounds by NMR spectroscopy was carried out within the framework of the Kazan Federal University Strategic Academic Leadership Program (PRIORITY-2030). |
