Cooperative recognition of Cu 2+ based on amino acids tethered benzothiadiazoyl-bistriazoles
Frontiers of Chemistry in China(2010)
摘要
Fluoroionophoric properties of benzothiadiazoyl-bistriazoyl amino acids derivatives toward metal ions were investigated by UV-Vis and fluorescence spectroscopy. Our results show that the watersoluble lysine derivative 2 exhibited a significant selectivity toward Cu 2+ in “on-off” type response in buffer solution at pH 7.4.
