摘要：A triphenylamine-based fluorescent probe 1 with larger Stokes shift (similar to 141 nm) has been synthesized, which can make an efficient nucleophilic addition by reacting with CN- in water. Upon addition of CN-, the red fluorescence of 1 was distinctly quenched. Importantly, 1 exhibits a highly selective response toward CN- over other anions in water and a high sensitivity (detection limit <= 11 nM). More-over, it has potential application to track CN- levels in living cells by confocal laser scanning microscopy (CLSM). (C) 2013 Elsevier Ltd. All rights reserved.
