a Excitation emission spectra of Ag3L3 and JNM-100 (blue and orange present PL spectra of Ag3L3 and JNM-100, respectively; dashed and solid lines represent excitation and emission spectra, respectively). b Fluorescence spectra of JNM-100 in the presence of an increasing concentration of Au(III) (from 0 to 10 μM) in water and methanol mixture (50:50 v/v%). Inset, profiles of the emission intensity versus Au(III) concentration showing a good linear relationship. c Comparison of the relative emission intensity ratio (I/I0) indicates indicating a good selectivity for Au(III) detection over 20 metal ions for JNM-100.
