title: Synthesis of Two Coumarin-Derived Schiff Bases and Investigation of theirs Selectivity for Zn2.
abstract: In this study, the coumarin-derived schiff bases (HL1and HL2) have been designed and synthesized. Upon the addition of Zn2+, both of them show significant fluorescence enhancement owing to inhibits PET and ESIPT process respectively. However, the receptor HL2response toward Cd2+, Mg2+, Ba2+, Ca2+besides Zn2+and exhibits fluorescence enhancement but not enough to detection of the concentration levels of Zn2+.
