A mononuclear iron(II) neutral complex (1) was screened for colorimetric sensing abilities for a wide spectrum of vapor-phase analytes including toxic gases. Although 1 possesses a single sensing unit without any other cross-reactive elements, it can capture information about analyte molecules in a distributed fashion that is encoded sufficiently to allow discrimination from other closely related chemical structures. Clear color differentiation among four different toxic industrial chemicals (TICs) and alcohols was demonstrated. Different TICs and alcohols were readily identified using a standard chemometric approach (hierarchical clustering analysis), with no misclassifications over 18 trials. ⁵⁷Fe Mössbauer spectroscopy was applied to investigate the driving spin state change of the analytes in this Fe-azole sensor material. This approach opens up perspectives for the further development of iron materials as potential optical sensor arrays through colorimetric techniques.

通用的基于铁（ii）的比色传感器，用于气相检测酒精和有毒气体†

筛选了单核铁（II）中性配合物（1）的比色传感能力，可用于多种气相分析物，包括有毒气体。尽管1具有单个传感单元，没有任何其他交叉反应元素，但它可以以分布式方式捕获有关分析物分子的信息，该信息经过充分编码，可以区别于其他紧密相关的化学结构。证明了四种不同的有毒工业化学品（TICs）和醇之间明显的颜色区分。使用标准的化学计量学方法（分层聚类分析）可以轻松识别出不同的TIC和酒精，在18个试验中没有错误分类。⁵⁷FeMössbauer光谱用于研究这种Fe-唑传感器材料中分析物的驱动自旋态变化。这种方法为通过比色技术将铁材料作为潜在的光学传感器阵列的进一步发展开辟了前景。
