A novel Cr3+ turn-on probe based on naphthalimide and BINOL framework
摘要:
Naphthalimide and BINOL framework based fluorescent probe NP-B was rationally designed and synthesized. NP-B exhibited 'turn-on' fluorescence for Cr3+ and high selectivity over other metal ions. 1:1 binding mode between NP-B and Cr3+ was proposed and the mode was verified through MALDI-TOF mass spectrum. The detection limit was calculated to be 0.20 mu M, which indicated the good sensitivity for Cr3+. (C) 2013 Elsevier Ltd. All rights reserved.
