title: Molecular binding behaviors and thermodynamics of ferrocenyl dimethylaminium derivatives by anionic pillar[5]arene.
abstract: A novel anionic water-soluble pillar[5]arene (4C-WP5A) was synthesized via a convenient synthetic strategy of the direct cyclization of a functionalized hydroquinone monomer. The alkyl chain dependent affinities of ferrocenyl aminiums (FCn(+), n: carbon number) with 4C-WP5A are driven by hydrophobic interactions and desolvations with assisted C-H···π interactions and electrostatic interactions.
