Synthesis, Spectroscopic Properties of Bis-Boc-L-Alanine Modified 1,8-Naphthyridine Ligand Induced by Hg²⁺

Abstract:

One Bis-Boc-L-alanine-1,8-naphthyridine ligand containing amino acid by amido bond named 2,7-Bis-Boc-L-alanine-1,8-naphthyridine (L1) was synthesized and characterized. And there absorption and fluorescence spectra in methanol is presented. It exhibits electronic absorption spectra with λmax at about 340 nm, which can be tentatively assigned to π→π* transition. The emission spectra of L1 in CH₃OH shows a mirror symmetry peak with λ_max at about 375 nm. Then, the comprehensive study of spectroscopic properties upon titration of L1 with heavy metal ions as ion source in CH₃OH was investigated.
