Sensor for nitrophenol based on a fluorescent molecular clip.
We report the synthesis, X-ray crystal structure, and photophysics of a fluorescent molecular clip (1). Binding studies of 1 toward phenols 2a-j were carried out using fluorescence, (1)H NMR, and IR spectroscopy, which revealed a high affinity and selectivity for 4-nitrophenol (2a) due to formation of the 1.2a complex driven by H-bonding and pi-pi stacking interactions.
