摘要

Based on thiourea moiety, three colorimetric and fluorescent anion probes have been synthesized. Results indicated the probe 1 containing p-NO2 group showed the strongest binding ability for AcO− among the anions tested (F−, AcO−, H2PO4-, Cl−, Br−, I−), which was not influenced by the existence of other anions. The interaction of host–guest was accompanied with a dramatic color change from colorless to orange. However, the ...
