摘要：A Schiff base derivative, N-(3-methoxy-4-hydroxybenzylidene)salicyloylhydrazone (L), shows high selectivity to Lu<sup>3+</sup>not only in abiotic systems but also in living cells with fluorescence. The presence of PVP can increase the fluorescence intensity. The fluorescence enhancement is presumably due to a combinational effect of intramolecular charge transfer (ICT) and excited-state intra/intermolecular proton transfer (ESPT) during the chelation of L to Lu<sup>3+</sup>in a 2:1 complex mode.<br/> © 2017 The Royal Society of Chemistry.
