苯胺蒸气的吸附检测因其潜在的节能性而有望取代现有的检测方法。在多孔材料中实现有效的选择性苯胺/BTEX吸附检测是具有挑战性的，因为缺乏功能位点。通过功能化，我们在本文中报告了一种羟基官能化的锆金属有机框架（UIO-66（OH）2），用于有效的选择性苯胺/苯系物检测。UIO-66-（OH）2在环境条件下显示出显著的苯胺/BTEX响应差异和选择性。模拟计算表明，-OH与苯胺的-NH 2基团之间的氢键作用增强了它们的选择性吸附。
Adsorptive detection of aniline vapor is desired for its potential energy-efficient on replacing current methods. Realizing efficient selective aniline/BTEX adsorptive detection in the porous materials is challenging because of the lack of functional sites. By virtue of functionalization, we herein report a hydroxyl functionalized zirconium metal-organic framework (UIO-66(OH)2) for the efficient selective aniline/BTEX detection. UIO-66-(OH)2shows a significant aniline/BTEX response difference and selectivity under ambient conditions. Simulative calculation indicates that the hydrogen bond interaction between –OH and the –NH2group of aniline enhances their selective adsorption.
