제목 Squarylium-Based Colorimetric Probe for the rapid and selective detection of Hydrogen Sulfide
초록 In this study, we developed a new colorimetric chemosensor (SQ1, SQ2, and SQ3) based on Squarylium for efficient H2S detection, and their detection properties were systematically characterized. SQ1 exhibited rapid and high resolution H2S sensing properties through significant color changes detectable by naked-eye with limit of detection as low as 7.2 ppb. SQ1 also showed highly selectivity for H2S detection over other relevant anions and nucleophiles. Sensing mechanisms of SQ1 were investigated based on spectroscopic and 1 H NMR analyses with quantum calculations. Furthermore, SQ1 showed an efficient response to H2S under versatile conditions in the solution, solid, and dyed fabric states, which suggests applicability of SQ1 to simple, low-cost, and practical H2S sensors
