Abstract

We have synthesized an open-cage C60 derivative having three hydroxy groups arranged in close proximity on the opening, which realized a single but hydrogen-bonded water molecule inside its cavity. The confined H2O molecule showed characteristic translational and rotational motions via the formation/cleavage of H-bonds. It is worth noting that the confined H2O molecule is less acidic and less basic than bulk water.

摘要

我们合成了一种具有三个羟基的开笼 C60 衍生物，这些羟基在开口处紧密排列，在其空腔内实现了单个但氢键结合的水分子。受限的 H2O 分子通过氢键的形成/断裂表现出特征性的平移和旋转运动。值得注意的是，受限的 H2O 分子的酸性和碱性均弱于体相水。
