Biotin[6]uril hexaesters represent a new class of anionophores which operate solely through C-H···anion interactions. The use of soft H-bond donors favors the transport of less hydrophilic anions (e.g., Cl(-), NO3(-)) over hard, stongly hydrated anions (e.g., HCO3(-) and SO4(2-)). Especially relevant is the selectivity between chloride and bicarbonate, the major inorganic anions in biological systems.
生物素[6]脲六酯代表了一类新型的阴离子载体，它们仅通过 C-H···阴离子相互作用起作用。软氢键供体的使用有利于运输疏水性较弱的阴离子（例如 Cl(-)、NO3(-)），而不是硬的、强水合的阴离子（例如 HCO3(-) 和 SO4(2-))。特别相关的是氯离子和碳酸氢根之间的选择性，它们是生物体系中主要的无机阴离子。
