Abstract:
In this paper, a novel tripodal fluorescent receptor based on naturally occurring coumarin was synthesized and its ionic recognition properties were fully investigated by spectroscopic techniques. As revealed by the results, tripodal 1 exhibits excellent selectivity toward copper(II) by forming a 1:1 complex with triazole N as the main binding sites. And the resulted 1·Cu2+ complex shows recognition ability toward H2PO4− by metal displacement approach. The recognition mechanism was further investigated by computer calculation.
