摘要：
The condensation product of L-alanine and salicylaldehyde was synthesised and characterised which was found to be selective fluorescent "on" sensor for Al3+ ion with the detection limit 10(-6) M. The sensor is free of interferences from metal ions - Na+, K+, Ca2+, Mn2+, Co2+, Ni2+, Cu2+, Pb2+, Cd2+, Hg2+ and Fe3+. The Fluorescence and the UV/visible spectral data reveals a 1:1 interaction between the sensor and Al3+ ion with binding constant 10(4.5). The DFT and TDDFT calculations confirm the structures of the sensor and the sensor-Al3+ complex.
