New Zn-II complexes with fluorescent ligand [Zn-(bpimp)(3)]X-2 (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 Zn-II complexes exhibit fluorescence in solution and solid states. On the other hand, Ni-II- and Co-II-bpimp complexes do not exhibit strong fluorescence in solution and in the solid states.
