Dual luminescence from a mixed-metal complex containing rhenium(I) and ruthenium(II) photochromophores

Abstract

Photophysical properties of the complex [(bpy)₂Ru(bpyen)Re(CO)₃(py)]³⁺[bpy = 2, 2′-bipyridine; py = pyridine; bpyen = 1,2-bis(4′-methyl-2,2′-bipyridyl-4-yl)ethane], show that the cation luminesces at 540 and 610 nm in methylene chloride at room temperature; the luminescence at 540 nm is derived from the Re luminophore component and that at 610 nm from the Ru luminophore component.
