The energy of excited state depended on the nature of different cations. 3. 4-(4-tolyl)-6-phenyl-2, 2'-bipyridine platinum acetylide complex containing a monoazazcrown moiety in the acetylide ligand could signal Mg〓 specifically and displayed large changes both in color and in luminescence intensity upon complexation with Mg〓. The most striking result was that it could signal Mg〓 specifically even in the presence of alkali and alkaline earth metal ions in high concentrations.
