Synthesis of Two Coumarin-Derived Schiff Bases and Investigation of theirs Selectivity for Zn2

In this study, the coumarin-derived schiff bases (HL 1 and HL 2 ) have been designed and synthesized. Upon the addition of Zn 2+ , both of them show significant fluorescence enhancement owing to inhibits PET and ESIPT process respectively. However, the receptor HL 2 response toward Cd 2+ , Mg 2+ , B...

Zusammenfassung:In this study, the coumarin-derived schiff bases (HL 1 and HL 2 ) have been designed and synthesized. Upon the addition of Zn 2+ , both of them show significant fluorescence enhancement owing to inhibits PET and ESIPT process respectively. However, the receptor HL 2 response toward Cd 2+ , Mg 2+ , Ba 2+ , Ca 2+ besides Zn 2+ and exhibits fluorescence enhancement but not enough to detection of the concentration levels of Zn 2+ .
