摘要：A ratiometric BINOL-based fluorescent probe for Zn2+ detection was rationally designed and synthesized. Based on the excited-state intramolecular proton transfer (ESIPT) mechanisms, the probe exhibited a significant variation on emission wavelengths with shifts more than 100 nm after combining with Zn2+, with emission colors changing from yellow to blue. Good selectivity and sensitivity of the probe toward Zn2+ could be found in aqueous solution. Sensing mechanism was proposed on the basis of fluorescence, absorption, ESI mass spectrometry, IR spectra, and CD spectra. (C) 2016 Elsevier Ltd. All rights reserved.
