文摘

The condensation product of phenylalanine and salicylaldehyde (L) was synthesised and characterised which was found to be selective fluorescent “off-on” sensor for Zn2+ ion with the detection limit 10−5 M. The sensor is free of interferences from metal ions - Na+, K+, Al3+, Mn2+, Co2+, Ni2+, Cu2+, Pb2+, Cd2+ and Hg2+. The Fluorescence and the UV/visible spectral data reveals a 1:1 interaction between the sensor and Zn2+ ion with binding constant 108. The DFT and TDDFT calculations confirm the structures of the sensor and the sensor-Zn2+ complex.KeywordsPhenylalanineFluorescenceSensorZincDFTTDDFT
