Photophysical properties and applications of Re(I) and Re(I)–Ru(II) carbonyl polypyridyl complexes

Rhenium(I) and technetium(I) complexes of a novel pyridyltriazole-based ligand containing an arylpiperazine pharmacophore: Synthesis, crystal structures, computational studies and radiochemistry

“…Re(CO) 3 complexes, which have been commonly used as a nonradioactive alternative to technetium complexes for macroscopic-scale synthesis and structural characterization, also could serve as luminescent probes. In this latter case, the tricarbonyl rhenium core was coordinated by heteroaromatic amine, e.g., diquinolinylamine (dqa) [2], or α,α′-diimine such as 2,2′-bipyridine [3].…”

“…In this latter case, the tricarbonyl rhenium core was coordinated by heteroaromatic amine, e.g., diquinolinylamine (dqa) [2], or α,α′-diimine such as 2,2′-bipyridine [3]. It is noteworthy that if Zubieta et al developed maleimide-dqa derivatives, leading to M(CO) 3 + complexes suitable for both imaging and radioimaging studies of proteins [4], the development of functionalized bipyridines still remains a significant challenge.…”

Within this context and aiming at the development of novel rhenium (I) and technetium(I) complexes as luminescent and/or radiopharmaceutical agents, we recently designed fluorescent rhenium(I) complexes from mono-functionalized 2-pyridyl-1,2,3-triazole derivatives (or pyta) as alternative ligands to 2,2′-bipyridines [5].…”

Syntheses, structures, and properties of tricarbonyl rhenium(I) heteronuclear complexes with the multidentate bridging ligand containing bis(2-pyridine) and carboxylic acid

“…p* (bpydt)) transition and/or LLCT (ligand-to-ligand charge transfer, Cl ? bpydt) transition [31,32,[43][44][45][46]. Compared to 2 and 3, complex 1 shows a blue shift of 6 nm as a result of the electron donor effect of -COOMe group [43,44].…”

Synthesis, characterization and photophysics of alkyne bridged bimetallic rhenium(I) and ruthenium(II) complexes

“…However, Ru(II) and Re(I) heterobimetallic dyads are relatively less, though few reports are available [31][32][33][34][35]. In the present study, we describe the synthesis, photophysics and electrochemistry of rigidly bridged bimetallic complexes of ruthenium(II) and rhenium(I).…”
