摘要：
Two novel thioxanthone-based compounds 1a and 1b which possess thiosemicarbazone as binding site were developed for the dual-channel detection of Hg2+ and F-. Upon treatment with Hg2+ and F- separately, the probes' fluorescence is effectively quenched, meanwhile 1a and 1b show evident naked-eye color variations after addition of F-: colorless to yellow. They both exhibit specific sensitivity and selectivity for Hg2+ or F- over other examined ions in tetrahydrofuran (THF) solution. (C) 2014 Elsevier Ltd. All rights reserved.
