초록
A bottom-modified (4-position) naphthalimide derivative 1 with 1,8-naphthyridine as binding site has been designed and synthesized. Compound 1 is the first 1,8-naphthyridine-modified naphthalimide-based sensor that can detect Hg2+ selectively with respect to ratiometric fluorescent change and blue shift in organic aqueous solution. The Job’s plot and FAB mass indicate that 1 formed a 1:1 complex with Hg2+. A top-modified naphthalimide derivative 2 with 1,8-naphthyridin as binding site has also been synthesized for comparison.
