T. Hayashita et al., Positioning dependent anion recognition by thiourea-based chromoionophoresvia hydrogen bonding in aqueous vesicle solutions, CHEM COMMUN, (9), 2000, pp. 755-756
A cationic vesicle interface exhibited a filter function for less hydrophob
ic anions, and highly selective anion recognition via hydrogen bonding was
achieved by thiourea-based chromoionophores (C-n-TU) located deep inside th
e vesicle.
