“…Noncovalent interactions are the holy grail in nature and are central to biology, chemistry, material science, and many more. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Unlike covalent interactions, noncovalent interactions range from angstroms to nanometers. [10] In creating large and complex molecular clusters, contributions from noncovalent interactions are enormous.…”

Noncovalent interactions due to the presence of heteroatoms in supramolecular compounds have gained a lot of attention. These different heteroatom-based supramolecular compounds have inspired us to examine the noncovalent interaction in the isolated host and host-guest complexes. In view of this, in the current manuscript, we investigated the stability and torsional energy barrier of different conformers of the ditopic receptor host 1,6-bis(2,6-bis(benzothiazol-2-yl) pyridine-4-yloxy) hexane (bbh). The conformer that is accompanied by intramolecular CÀ H⋯N and CÀ H⋯S interactions is relatively more stable than the others. Due to torsional angle rotation within the host, the CÀ H⋯N and CÀ H⋯S interactions get disrupted and exhibit different binding sites for capturing guest molecules. In addition, we have extended the investigation to understand the interaction energy and nature of interaction in host-guest (1 : 1 and 1 : 2) complexes formed between the host (bbh) and guest (resorcinol) by using different DFT functionals. Extended transition state-natural orbital chemical valence (ETS-NOCV) analysis of complexes revealed that the electrostatic interaction significantly contributes to the host-guest interaction energy. The noncovalent (NCI) analysis provides the existence of intermolecular hydrogen bonding and other weak interactions within the complexes.

“…2,9,10 The significance of the effect of hydrophobicity, nature, structure of components, and electrostatic interactions during the association of reagents with surfactant counterions on the stability of associates is important. 11,12 Strengthening of electrostatic interactions and reduction of the role of hydrophobic interactions between associate-forming particles during solubilization is significant.…”

The influence of sodium hexadecyl sulfate on the nature of the fluorescence spectra of rhodamine 6G in an aqueous solution and a solution of nonionic Triton X-100 was investigated. The change in the nature of the emission spectra is explained by the formation of hydrophobic stoichiometric and substoichiometric reagent-surfactant associates. Stabilization of the colloid-chemical state and reduction of the total turbidity of rhodamine 6G – anionic surfactants associates solutions with the addition of nonionic surfactant as a modifier were registered. The method of modification of the rhodamine 6G – sodium hexadecyl sulfate system with a nonionic surfactant was used in the development of conditions for the fluorescence determination of protein substances in physiological solutions. The concentration conditions for the use of the modified reagent system rhodamine 6G – anionic surfactant – nonionic surfactant for the fluorescence determination of albumin in urine were optimized.
