ZnII Complexes Coordinated by Fluorescent Ligand 2-(4-tert-Butylphenyl)imidazo[4,5-f]-1,10-phenanthroline

Abstract New ZnII complexes with fluorescent ligand [Zn(bpimp)3]X2 (bpimp: 2-(4-tert-butylphenyl)imidazo[4,5-f]-1,10-phenanthroline) were prepared. While the ligand does not exhibit fluorescence in the solid state, the new ZnII complexes exhibit fluorescence in solution and solid states. On the other hand, NiII– and CoII–bpimp complexes do not exhibit strong fluorescence in solution and in the solid states.
