title = "Thiourea-isothiouronium conjugate for strong and selective binding of very hydrophilic H2PO4- anion at the 1,2-dichloroethane-water interface",
abstract = "Potential use of a surfactant-like receptor is demonstrated at the 1,2-dichloroethane-water interface for strong and selective binding of H 2PO4- over Br- and Cl-. The analysis by interfacial tensiometry reveals that the interfacial adsorption of a thiourea-isothiouronium conjugate, BT-C1, is significantly stabilized by the binding of H2PO4- with the adsorption constant of 1.7×105M-1 while the interfacial adsorptivity of this receptor is relatively moderate for Br - (0.81×105M-1) and Cl- (0.63×105M-1). Such complexation-induced interfacial adsorption behaviors of BT-C1 are discussed as a basis for the development of receptor-based chemical sensors for phosphate anions.",
