Abstract

In the present work, we first described the stable entrapment of the superoxide ions in gamma-irradiated (Me(4)NOH + O(2)) clathrate hydrate. Owing to peculiar direct guest-guest ionic interaction, the lattice structure of gamma-irradiated (Me(4)NOH + O(2)) clathrate hydrate shows significant change of lattice contraction behavior even at relatively high temperature (120 K). Such findings are expected to provide useful information for a better understanding of unrevealed nature (such as icy nanoreactor concept, ice-based functional material synthesis and lattice tuning by specific ionic guests) of clathrate hydrate fields.

摘要

在本工作中，我们首先描述了超氧离子在γ辐照（Me(4)NOH + O(2))包合物水合物中的稳定捕获。由于特殊的直接客体-客体离子相互作用，γ辐照（Me(4)NOH + O(2))包合物水合物的晶格结构即使在相对较高的温度（120 K）下也表现出显著的晶格收缩行为变化。这些发现有望为更好地理解包合物水合物领域未被揭示的性质（如冰纳米反应器概念、基于冰的功能材料合成和特定离子客体的晶格调谐）提供有用的信息。
