Fine-Tuning Metal and Ligand-Centered Redox Potentials of Homoleptic Bis-Terpyridine Complexes with 4′-Aryl Substituents

Homoleptic transition-metal complexes of 2,2':6′,2″-terpyridine (terpy) and substituted derivatives of the form [M(R-terpy)2]2+ display a wide range of redox potentials that correlate well to the Hammett parameter of the terpy substituents. Less is known about the impact of incorporating a phenyl spacer between the functional group responsible for controlling the electron density of terpy and how that translates to metal complexes of the form [M(4′-aryl-terpy)2]2+, where M = Mn, Fe, Co, Ni, and Zn. Herein, we report our studies on these complexes revealed a good correlation of redox potentials of both metal- and ligand-centered events with the Hammett parameters of the aryl substituents, regardless of aryl-substitution pattern (i.e., the presence of multiple functional groups, combinations of withdrawing and donating functional groups). The phenyl spacer results in 60-80% attenuation of electron density as compared to the 4′-substituted terpy analogue, depending on the metal and redox couple analyzed. Density functional theory calculations performed on a simple model system revealed a strong correlation between the Hammett parameters and lowest unoccupied molecular orbital energies of the corresponding substituted pyridine models, thus serving as an inexpensive predictive tool when coupled with electrochemical data. Overall, these data suggest that such ligand modifications may be used in combination with previous approaches to further fine-tune the redox potentials of homoleptic transition-metal complexes, which may have applications in photochemical and electrochemical catalytic processes.

Fine tuning of the photoinduced energy transfer rate in trinuclear Ru/Os 2,2′:6′,2″-terpyridine complexes through structural modification of the periphery

Trinuclear OsRu2 complexes were prepared and the role of peripheral thienyl units was investigated. The presence of the substituent was found to control energy transfer from ruthenium to osmium. A mononuclear complex was chosen as a spectroscop

Synthesis, DNA interaction and anticancer activity of copper(II) complexes with 4′-phenyl-2,2′:6′,2″-terpyridine derivatives

Three novel copper(II) complexes CuL1Cl2 (1) (L 1 = 4′-(3-methoxyphenyl)-2,2′:6′- 2″-terpyridine), CuL2Cl2 (2) (L2 = 4′-(4-methoxyphenyl)-2,2′:6′-2″-terpyridine) and CuL3Cl2

Metal-directed synthesis and photophysical studies of trinuclear V-shaped and pentanuclear X-shaped ruthenium and osmium metallorods and metallostars based upon 4'-(3,5-dihydroxyphenyl)-2,2':6',2"-terpyridine divergent units

A new series of V-shaped trinuclear metallorods and X-shaped pentanuclear metallostars has been prepared by the reaction of metal complexes bearing pendant phenolic functionalities with complexes containing electrophilic ligands. Specifically, {M(tpy)sub

Compositions and methods for separating heterocyclic aromatic amine bases, nucleosides, nucleotides, and nucleotide sequences

The compositions of the present invention comprise one or more palladium bound ligands that are covalently bonded to inorganic or organic solid supports. These palladium bound ligands bonded to solid supports can be used for single heterocyclic amine base separation, or can be used to separate nucleotide chain containing specific sequences from other nucleotides or nucleotide chains. In one aspect of the invention, each ligand present is individually complexed to a single Pd(II) ion. If there are from 2 to 4 ligands present in the composition, then each ligand present must be separated from the other ligands by at least 3 atoms, preferably from 3 to 20 carbon atoms or equivalent spacing.
