Synthesis and Determination of Al3+ in Chinese Herbs from Heilongjiang Province by Fluorescent Probe of Naphthalimide

We reported a new naphthalimide fluorescence probe M1[dimethyl 3, 3'-((2-((2-butyl-1, 3-dioxo-2, 3-dihydro-1H-benzo[de] isoquinolin-6-yl) amino) ethyl) azanediyl) dipropionate] with Al3+ system. Its UV-visible absorption spectrum and showed remarkable optical characteristics. The optimal experimental conditions, including reaction temperature, pH, time were investigated. This system possessed good anti-interference ability toward the other 16 metal ions. M1 shows linearity concentration (1 × 10-6 ~ 15 mol/L). LOD (Limit of Detection) was 7.55 10-8 mol/L. It has resistance to interference. excellently resistant interferences. complexation ratio between is 1:1. Furthermore, binding mechanism conjectured. applied constructed for first determination in Chinese herbal medicines, imaging living cells.
