Open-cage fullerenes as tailor-made container for a single water molecule

Water is the most important liquid on earth. Clusters of water have been investigated extensively in an effort to understand the bulk property of water. But the behavior of single water molecule without H-bond has been rarely studied. Open-cage [60]fullerenes have been shown to trap a single water molecule selectively over molecules with comparable size and act as the smallest water bottle.
