Abstract: A new fluorescent sensor 1 was designed and synthesized through the condensation of indole-3-aldehyde and N-(2-hydroxyethyl)ethylenediamine. It exhibits good sensitivity and selectivity for the copper cation over other cations such as K+, Na+, Ca2+, Cr2+, Mg2+, Zn2+, Al3+ and Fe3+. The fluorescence intensity of the sensor was decreased with increasing the concentration of Cu2+. The analysis of the Benesi-Hildebrand equation indicated the formation 1:1 complex of 1 and Cu2+ with association constant Kass=3.34×105M.
