Abstract:
A new thiophene hydrazide derivative TSB was synthesized and utilized as naked-eye colorimetric sensor for Cu2+ by the color changed from colorless to yellow as well as green fluorescent turn on sensor for Al3+ in DMSO/H2O (1/1, V/V) solution. The dual-functional chemosensor TSB for Cu2+/Al3+ sensing displayed excellent properties of special selectivity, superior sensitivity, outstanding anti-interference performance, instantaneous response, wide pH working range and good reversibility. The detection limits of TSB for Cu2+/Al3+ were determined as low as 46.5 nM and 32.7 nM, respectively. The 1:1 binding mode of TSB with Cu2+/Al3+ was proved by spectrometric titrations, Job's plots, FTIR, 1H NMR and HRMS analysis. Moreover, chemosensor TSB was successfully utilized for detection of Cu2+ and Al3+ in real environmental water and food samples with high reliability, demonstrating its practical applicability.
