Abstract

original image

Ein zweizähniger Bromimidazoliophan-Rezeptor bindet in konkurrierendem wässrigem Medium selektiv Bromid-Ionen (siehe Bild: grau=Kohlenstoff, blau=Stickstoff, braun=Brom) über kooperative konvergente Halogenbrücken zwischen den Bromid-Ionen und den Brom-Atomen des Rezeptors.
