Inclusion of Carboxyl Function Inside of Cucurbiturils and its Use in Molecular Switches

Popis výsledku v původním jazyce

We have prepared organic guest molecules in which two pyridinium rings are connected through an aromatic/aliphatic bridge bearing a carboxyl group. The supramolecular interactions between these guests and macrocyclic hosts cucurbit[7]uril (CB7) and cucurbit[8]uril (CB8) has been studied. We have demonstrated that the binding modes of the complexes depend on type of central bridge present in guest molecules and the size of the the the macrocycle. We have also showed that the binding mode between cucurbiturils and guests with aromatic bridges is pH independent. On the other hand, a guest containing an aliphatic bridge and CB7 formed a pseudorotaxane, which behaved as a pH-driven molecular switch.
