The recent use of noble gases in laser devices and semiconductor lithography has greatly increased. However, there is no commercial technology for the storage of noble gases in solid materials owing to their chemical inertness and relative lightness. Here we report the simple synthesis and characteristics of a hydroquinone clathrate that stably captures neon at atmospheric pressure and room temperature. The highly flexible structure enables neon encapsulation in the one-dimensional channels of the clathrate framework despite their inter-cage migration through the hexagonal entrance of the cages. The neon uptake of as-synthesized hydroquinone clathrates is 37.3 g L⁻¹ at 1 bar and 298 K. Increasing the temperature accelerates the release of neon from the flexible hydroquinone clathrate hydrogen-bonded organic framework, leading to guest-free clathrate formation at 1 bar and 400 K. This method represents a technological development for better storage and the controlled release of noble gases in solid structured materials.

最近，稀有气体在激光器件和半导体光刻中的使用大大增加。然而，由于惰性气体的化学惰性和相对较轻，目前尚无用于在固体材料中存储惰性气体的商业技术。在这里，我们报道了在大气压和室温下稳定捕获氖的氢醌笼形物的简单合成和特性。尽管氖通过笼的六角形入口在笼间迁移，但高度灵活的结构使得氖能够封装在笼形框架的一维通道中。合成时对苯二酚笼形物的氖吸收量为 37.3 g L ^-1在 1 bar 和 298 K 下。提高温度会加速氖从柔性对苯二酚笼形物氢键有机框架中的释放，导致在 1 bar 和 400 K 下形成无客体笼形物。该方法代表了更好储存和储存的技术发展。固体结构材料中惰性气体的受控释放。
