摘要
Anthracene labeled pyridine amide receptors 1-3, which can function as fluorescence switch towards monocarboxylic acids, have been designed and synthesized. The photophysical behaviors have been examined by fluorescence, UV-vis and NMR spectroscopy in the presence and absence of monocarboxylic acids of different acid strengths. While the emission of receptor 1 is decreased in the presence of monocarboxylic acids, the receptors 2-3, on the contrary, show the reverse behavior under similar conditions.
