Increasing emissions of volatile organic compounds (VOCs) and their resulting impact on air and water quality has become one of the major environmental concerns of our age, especially in industrialized societies. Some VOCs are identified as highly toxic or carcinogenic, and may impact human health as well as on the natural ecosystem. VOCs are emitted from the use of many everyday household products, which makes the control of their emissions particularly difficult and critical. One of these VOCs is acetonitrile, which is primary used as an organic solvent in extractive processes, and it is also commonly used for dyeing textiles, as a metal cleaner and for battery applications. Exposure to acetonitrile occurs mainly through inhalation and dermal contact in workplaces in which acetonitrile is produced or used. Toxicological studies have provided sufficient evidence that high levels of acetonitrile induce potential neurotoxicity, nausea, impaired motor activity, shallow and/or irregular respiration and, in extreme cases, death.
Currently, highly sensitive analytical techniques are employed for the accurate quantification of VOCs, often based on optical absorption, particle counting or mass spectrometry. However, these techniques have some drawbacks, such as their low portability, constrained selectivity, complex and time-consuming pre-treatment steps, necessity of highly skilled operators and high cost. To overcome these limitations and explore more cost-effective alternatives, such coordination polymers have attracted a great deal of attention in the development of next-generation sensing devices. These...
