Abstract

Abstract : Salicylaldehyde azine (1 ), with an aggregation-induced emission (AIE) function, was synthesized from salicylaldehyde and characterized by nuclear magnetic resonance, high resolution mass spectrometry, and X-ray single crystal diffraction. Abstract : Salicylaldehyde azine (1 ), with an aggregation-induced emission (AIE) function, was synthesized from salicylaldehyde and characterized by Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance (NMR), high resolution mass spectrometry (HRMS), and X-ray single crystal diffraction. Compound1 exhibited high thermal stability and good light-emitting behavior in the solid state. It could be preferably used to dye cellulose and KBr. No obvious changes in fluorescence intensity occurred when compound1 was dissolved in different pH buffer solutions. The addition of TFA led to slight fluorescence quenching, and the fluorescence intensity gradually increased with increasing potassium tert -butoxide solution concentrations. The fluorescence intensity of compound1 showed a good linear relationship with the concentration of potassium tert -butoxide (0.5–4.0 × 10 −4 M), y = 99.193 x + 93.599, R 2 = 0.9902; the limit of detection (LOD) was 1.07 × 10 −7 M. It could measure the content of potassium tert -butoxide with a relative standard deviation (RSD) value of 1.5%.
