second transition metal center. The protonated forms of these “rolled-over” Ir(III) complexes were isolated in a straight-forward procedure using trifluoroacetic acid. The photophysical, photochemical and electrochemicalproperties of both the protonated and unprotonated Ir(III) complexes were investigated by steady-state and time-resolved spectroscopies, as well as by density functional theory calculations
A microwave-assisted synthesis of photosensitive iridium(III) polypyridine complexes has been developed. The spectroscopic and electrochemical properties of the newly prepared complexes were studied. These complexes were characterized by intense phosphorescence emission from 505 nm to 630 nm.

The versatile new precursor to bis-2,2′-bipyridine complexes of IrIII, cis-[IrIII(bpy)2(OSO2CF3)2][CF3SO3](bpy = 2,2′-biyridine), has been isolated and used for the preparation of the new hydrido complexes of IrIII, cis-[Ir(bpy)2(PPh3)H][PF6]2 and cis-[Ir(bpy)2H2][PF6], and for an improved, high-yield synthesis of [Ir(bpy)3][PF6]3.
