Anthracene-isothiouronium salts, Anion sensing
Novel fluorescent anion chemosensors based on anthracene-isothiouronium derivatives were synthesized. Isomerism due to the intramolecular mobility in these isothiouronium salts was detected by 1H NMR spectroscopy. The effect of the substituent, temperature and solvent on the isomerism was also examined. The anthracene-isothiouronium sensor showed significant fluorescent enhancement upon the addition of various anions such as fluoride, acetate, and dihydrogen phosphate, even in the presence of water.
