제목 Highly Sensitive, Selective, and Rapid Response Colorimetric Chemosensor for Naked Eye Detection of Hydrogen Sulfide Gas under Versatile Conditions: Solution, Thin-Film, and Wearable Fabric
초록 In this study, we developed a new colorimetric chemosensor (C8-ISPBI) based on isatin Schiff base for efficient H2S gas detection. C8-ISPBI allowed highly sensitive (limit of detection: 43.1 ppb), rapid (detection time<15s), and highly selective H2S detection in solution by exhibiting color changes discernable with the naked eye. Based on systemic characterization, including of UV-Vis absorption and NMR spectral analyses, as well as theoretical calculations, we reveled that the H2S sensing capability of C8-ISPBI originated from nucleophilic attack reactions. C8-ISPBI also exhibited excellent H2S detection under practical conditions, such as film-coated paper strip and dyed wearable textiles. These advantageous sensing properties suggests the practical applicability of C8-ISPBI to the simple but very effective H2S gas sensor platform under versatile conditions.
