Abstract:
In this work, the formation of two- and three-component
supramolecular systems based on cone, partial cone, 1,3-alternate stereoisomers of heteroditopic “hosts”: p-tert-butylthiacalix[4]arene containing
4-amidopyridine fragments with silver(I) cations and dicarboxylic acids in
liquid and solid phases were studied by UV spectroscopy, dynamic light
scattering, and atomic force microscopy methods. It has been shown that these
macrocycles are coreceptors, capable of simultaneously binding silver(I)
cations, dicarboxylic acids (oxalic, malonic, succinic, maleic, fumaric acids),
and hydroxyl acids (glycol, tartaric acids). For the first time, by the dynamic
light scattering method, it has been shown that the conformation of p-tertbutyl thiacalix[4]arenes significantly affects the type of three-component
system formed: cone is characterized by the formation of cascade systems; for partial cone, intermediate systems; and for the
1,3-alternate stereoisomers, three types of three-component systems (cascade, intermediate, and commutative) were observed
