摘要: Abstract A 1,8-naphthalimide–Cu(II) ensemble was rationally designed and synthesized as a new turn-on fluorescent probe utilizing the ‘chemosensing ensemble’ method for detections of thiols (Cys, Hcy GSH) with high selectivity over other α-amino acids at pH 7.4 in organic aqueous media (EtOH/HEPES, v/v = 9:1). The recognition mechanism attributed to remove Cu(II) from by release flurescence ligand 1 . Remarkable fluorescence enhancements were therefore observed sensing process ensemble. Furthermore, successfully applied imaging CHO cells sensitivity selectivity.
