Synthesis and Metal Ion Probe Properties of Four 1,8-Naphthalimides

摘要

Four 1,8-naphthalimide derivatives (3a-3d) were designed and synthesized from 1,8-naphthalic anhydride and their structures were characterized by ~1H NMR and MS. Their recognition ability to metal ions was then investigated. The results showed the quenching constants (K_(cv)) and binding constants (K_a) values were found in the range of 10~2-10~4 M~(-1) indicating important metal ions recognition abilities of compounds 3a-3d. All the compounds showed recognition of ferric ion, while compounds 3a-3d showed the best recognition ability of silver, cadmium, ferric and ferrous ions, respectively.
