Decoding the Interplay of Hydrogen Bonding, Dispersion, and Steric Interactions in Conformational Isomerism Among Functionalized Pillar[n]arenes.

ABSTRACT: Pillar[n]arenes have garnered popularity due to their unique pillar-shaped structure, which results in hydrophobic cavities. These cavities facilitate the formation of inclusion complexes with guest molecules through non-covalent interactions such as π - π stacking, hydrogen bonding, and van der Waals interactions. Such host-guest interactions enable diverse functionalities in pillar[n]arenes, including molecule recognition, self-assembly, and encapsulation. Nevertheless, it is important to note that the host-guest properties of pillar[n]arenes can be influenced by conformational changes, primarily driven by the rotation of hydroquinone units about their methylene bridge axis. These structural changes can lead to variations in underlying non-covalent and steric interactions, impacting the
