Versatile self-assembled molecular capsule formation of a resorcin[4]arene-based benzamidoiminocavitand.
The facile synthesis of a resorcin[4]arene-based imino-cavitand with benzamido moieties and its self-assembly into molecular capsules are reported. Benzamido-iminocavitand efficiently self-assembled into thermally inert molecular capsules in the presence of suitable guests via the eight intermolecular N-H···O=C hydrogen bonds.
متن کاملSelf-recognition, structure, stability, and guest affinity of pyrogallol[4]arene and resorcin[4]arene capsules in solution.
In the present study, we used diffusion NMR to probe the structures and characteristics of the products obtained from the self-assembly of resorcin[4]arenes 1a and 1b and pyrogallol[4]arenes 2a and 2b in CDCl(3) solutions. It was found that all four molecules self-assemble into hexameric capsules. The hexameric capsules of pyrogallol[4]arenes 2a and 2b were found to be more stable than the caps...
متن کاملHydrogen-Bonded Hexameric Capsules of Resorcin[4]arene, Pyrogallol[4]arene and Octahydroxypyridine[4]arene are Abundant Structures in Organic Solvents: A View from Diffusion NMR
Hydrogen-bond molecular capsules have attracted much interest in the last decade. In the present paper, we wish to describe new insights obtained from diffusion NMR when studying the self-assembly of resorcin[4]arenes (2), pyrogallol[4]arenes (3) and octahydroxypyridine[4]arenes (4) in solution. These diffusion NMR studies demonstrate that compounds 2 and 3 self-assemble spontaneously into hexa...
متن کاملImmobilization of [60]fullerene on silicon surfaces through a calix[8]arene layer.
In this work, we report the functionalization of flat Si(100) surfaces with a calix[8]arene derivative through a thermal hydrosilylation process, followed by docking with [60]fullerene. Chemical grafting of calix[8]arene on silicon substrates was evaluated by X-ray photoelectron spectroscopy, whereas host-guest immobilization of fullerene was demonstrated by atomic force microscopy and sessile ...
متن کاملThe effect of alcohol structures on the interaction mode with the hexameric capsule of resorcin[4]arene.
After more than a century of research on resorcin[4]arenes (1) it is clear that such systems form spontaneously [1(6)(H(2)O)(8)]-type hexameric capsules in wet, non-polar, organic solvents. However, the interactions of these hexameric capsules with alcohols are far from being solved. Here we provide the results of an extensive study on the interaction of different alcohols with the hexameric ca...
