Metal–organic frameworks (MOFs) are poised to improve modern-day gas sensors. Their unparalleled tunability and chemical selectivity across a wide span of chemical species have made them attractive for use in highly selective gas sensors. In this work, we delve into one of the biggest strengths of many MOFs, their irreversible chemisorption of gas molecules, and how this can be leveraged to create unique, low cost irreversible gas sensors (dosimeters) enabled by changes in MOF electrical properties. On the other hand, robust chemical bonding to the sensor substrate is often one of the biggest practical challenges facing MOF sensors for long-life applications. “Hold on tight”, be it to adsorbed molecules or the substrate itself, is a key factor in development of future MOF gas sensors. With continued advances, MOF materials are positioned to make both highly innovative and significantly impactful improvements to highly selective gas sensors used throughout society.

紧紧抓住：基于 MOF 的不可逆气体传感器

金属有机框架 (MOF) 有望改进现代气体传感器。它们在广泛的化学物种中无与伦比的可调性和化学选择性使它们在高选择性气体传感器中具有吸引力。在这项工作中，我们深入研究了许多 MOF 的最大优势之一，即它们对气体分子的不可逆化学吸附，以及如何利用这一优势来创建独特、低成本的不可逆气体传感器（剂量计），这些传感器可以通过 MOF 电特性的变化实现。另一方面，与传感器基板牢固的化学键合通常是 MOF 传感器在长寿命应用中面临的最大实际挑战之一。“紧紧抓住”，无论是吸附分子还是基板本身，都是未来MOF气体传感器发展的关键因素。随着不断的进步，
