A bis-exTTF macrocyclic receptor that associates C60 with micromolar affinity.
An exTTF-based macrocyclic receptor that associates C(60) with a binding constant >10(6) M(-1) in chlorobenzene at room temperature is described. This represents an improvement of 3 orders of magnitude with respect to the previous examples of exTTF-based receptors and one of the highest binding constants toward C(60) reported to date.
