The spectroscopic properties for a recently synthesized hetero-metallobinuclear complex Ru(bpy)₂ (bpy-cyclam-Ni)⁴⁺ (3) and its related complexes 1 and 2 were investigated by UV-vis and emission spectral methods.A drastic quenching offluorescence from the Ru(bpy)₃²⁺ subunit by the covalently attached quencher subunit Ni(cyclam)²⁺ was observed for complex 3, and the mechanism was discussed.
