Abstract

Sensors that can accurately assess oxygen (O) concentrations in real time are crucial for a wide range of applications spanning personal health monitoring, environmental protection, and industrial process development. Here a high-performance chemiresistive sensor that allows for the rapid detection of O at room temperature under visible light illumination is described. Inspired by the operating principles of dye-sensitized solar cells, the chemiresistor is based on a single-walled carbon nanotube-titania hybrid (SWCNT-TiO) bearing a molecular Re-based photosensitizer [(bpy)(CO)ReBr] (bpy = 4,4'-[P(O)(OH)]-2,2'-bipyridine). The resulting SWCNT-TiO-Re composite undergoes photoinduced charge transfer that is sensitive to ppb levels of O, thereby yielding a rapid and reversible chemiresistive response. Owing to its unique mode of operation and robust components, the sensor shows a high degree of selectivity for O over a range of interferants, humidity tolerance, and multimonth benchtop stability. The approach presented herein demonstrates the translatability of concepts in light harvesting to the development of robust, rapid, and low-power sensing technologies.

摘要

能够实时准确评估氧气（O）浓度的传感器对于个人健康监测、环境保护和工业过程开发等广泛应用至关重要。本文描述了一种高性能的化学电阻传感器，它能够在可见光照射下于室温下快速检测氧气。受染料敏化太阳能电池工作原理的启发，该化学电阻器基于负载分子铼基光敏剂[（bpy）（CO）ReBr]（bpy = 4,4'-[P（O）（OH）]-2,2'-联吡啶）的单壁碳纳米管-二氧化钛复合材料（SWCNT-TiO）。所得的SWCNT-TiO-Re复合材料经历对氧气的ppb水平敏感的光致电荷转移，从而产生快速且可逆的化学电阻响应。由于其独特的操作模式和坚固的组件，该传感器在一系列干扰物中对氧气表现出高度的选择性、耐湿性和数月的台式稳定性。本文提出的方法证明了光捕获概念在开发强大、快速和低功耗传感技术方面的可转化性。
