Abstract

The control of air quality is of great importance, in particular for the protection of individuals and workers who can be exposed to harmful gases. We here describe innovative chemical and colorimetric sensors for the detection of nitrogen trichloride, NCl₃ a pollutant present in indoor swimming pools. These sensors are nanoporous matrices doped with specific probe-molecules, which can efficiently react with NCl₃. They act as sponges to trap the targeted pollutant and turn from transparent to pink-violet. These sensors can detect NCl₃ at ppb level within 15 minutes in humid atmosphere and ambient temperature of indoor swimming pools.
