An indolocarbazole trimer that consists of three indolocarbazoles linked by butadiynyl units has been prepared as an anion receptor (see picture). This trimer folds into a helical conformation upon anion binding by multiple hydrogen bonds. Compared with its analog that has shorter ethynyl linkers, the receptor shows much increased affinities to large anions such as dihydrogen phosphate and acetate.
