Two thioxanthone-based fluorescent probes exhibited prominent solvatofluorochromism, and they were further found to be useful as fluorescence indicators for the qualitative and quantitative detection of low-level water content in various solvent media.
Hydrochromism of thioxanthylium cations/ thioxanthene-9-ol can be tuned by structural functionalization to offer diverse colors and moisture-sensitivities. This reversible hydrochromic system is easily activated with organic acid from chemically stable precursors, allowing for possible uses in moisture-sensing and anti-counterfeiting encryption.
