| Abstract: | A hydrazide based covalent organic polymer (COP) with pyridine functionalities has been synthesized and used to fabricate an efficient chemosensor for the detection of gaseous H2S at 25 °C through a proton conduction process. The gas sensing behavior of the COP has been measured in a dynamic flow-through resistance measurement system. The COP fabricated sensor shows a lower response time of 9 s with a recovery time of 12 s, when the experiment is performed with a H2S concentration of 200 ppm at 25 °C. It also shows high selectivity to H2S gas compared to other gases such as CO2, NH3, CO and NO2. This journal is © The Royal Society of Chemistry. |
