Mixed-Ligand Complexes of Ruthenium(II): Factors Governing Binding to DNA

Binding and spectroscopic parameters for a series of mixed-ligand complexes on binding to DNA have been determined.The application of mixed-ligand complexes permits the variation in geometry, size, hydrophobicity, and hydrogen-bonding ability by systematic variation of complex ligands and the determination of how these factors contribute to DNA binding affinity.Ligands employed include 2,2′-bipyridine (bpy), 1,10-phenanthroline (phen), 4,7-diphenylphenanthroline (DIP), 5-nitrophenanthroline (5-NO2-phen), 4,5-diazafluorene-9-one (flone), and 9,10-phenanthrenequinonediimine (phi).Measurements include equilibrium binding isotherms and enantioselectivities associated with binding, the degree of absorption hypochromism and red shift in the ruthenium charge-transfer band, increases in emission intensities and excited-state lifetimes, perturbations in excited-state resonance Raman spectra (which reflect changes in excited-state charge-transfer distributions as a result of binding to DNA), and determinations of helical unwinding.The complexes examined, with the exception of Ru(bpy)32+, all appear to intercalate and surface-bind to DNA, and for those that bind appreciably, enantioselectivity is observed.Based upon the measurements of spectroscopic properties and binding isotherms, the intercalating ability appears to increase over the series bpy<Quality Control of: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II).

Energy transfer dynamics in multichromophoric arrays engineered from phosphorescent PtII/RuII/OsII centers linked to a central truxene platform

A rigid star-shaped tetrachromophoric trimetallic complex engineered from a 5,5?,10,10?,15,15?-hexabutyltruxene platform functionalized in the 2,7,12 positions with three different metal centers, namely, a terpyridine-Pt(II) ethynylene unit and Ru(II) and Os (II) bipyridine centers, was synthesized in a controlled fashion and characterized by 1H NMR and mass spectrometry. The protocol was devised in such a way that key mono and dinuclear model complexes and two reference truxene ligands could also be prepared. Room temperature (RT) optical absorption and RT and 77 K luminescence studies were performed on the truxene ligands, the trimetallic species, the various mono- and binuclear complexes and precursors lacking the truxene fragment; RT nanosecond transient absorption measurements were also carried out in particular cases. The electronic properties of the Ru and Os subunits in the arrays were found to be unaffected by the presence of the truxene core whereas direct linking of the Pt subunit to the truxene via the ?-alkyne bond markedly influences the spectroscopic behavior of the Pt center. Remarkably the truxene phosphorescence was clearly established in the two ligands (lifetime of 4.3 s for the mono ethynyl-bipy substituted truxene and 17.5 ms for the bis ethynyl-bipy substituted truxene) and also detected in the Pt-containing complexes PtL? (model Pt-truxene) and Pt-Os (Pt-truxene-Os dyad) at low temperature. This is attributed to the closeness in energy of the Pt 3CT level and the truxene triplet at low temperature and to the spin-orbit coupling induced by the Pt heavy atom. Transient absorbance measurements evidenced the population of the Pt-based triplet in the Pt-truxene mononuclear complex PtL? at room-temperature. For the trimetallic complex, where the various centers exhibit an energy gradient for the local excited levels, and following an approach based on the use of selected excitation of the components, an initial energy transfer was found to occur from the central truxene unit toward the peripheral Pt, Ru, and Os metal-based centers. Subsequent Pt-based and Ru-based excited state depletion contributes to the final sensitization of the low-lying Os triplet excited state; the excited state dynamics for these multicascade processes are examined in detail.

New trimetallosupramolecular Ru(II) complexes containing ferrocenylpyrazole subunits

A series of bi-, tri-, and tetradentate acyclic redox-active ligands containing one or two ferrocenylpyrazole subunits and one or two pyridines, differently organized, have been prepared. Starting from Ru(bpy)2Cl2, mono- and bi-Ru(II) complexes have been obtained. Their study by NMR spectroscopy, electrochemistry, and molecular modeling shows important structural variations according to the relative position of the ferrocenyl substitutent and of the coordination site. The ferrocenylpyrazole seems to be a good moiety for electronic transfers and the interaction between metallic centers depends strongly on the ligand structure. CNRS-Gauthier-Villars.

Improved Infrared Spectra Prediction by DFT from a New Experimental Database

This work aims to improve the computation of infrared spectra of gas-phase cations using DFT methods. Experimental infrared multiple photon dissociation (IRMPD) spectra for ten Zn and Ru organometallic complexes have been used to provide reference data for 64 vibrational modes in the 900?2000 cm?1 range. The accuracy of the IR vibrational frequencies predicted for these bands has been assessed over five DFT functionals and three basis sets. The functionals include the popular B3LYP and M06-2X hybrids and the range-separated hybrids (RSH) CAM-B3LYP, LC-BLYP, and omegaB97X-D. B3LYP gives the best mean absolute error (MAE) and root-mean-square error (RMSE) values of 7.1 and 9.6 cm?1, whilst the best RSH functional, omegaB97X-D, gives 12.8 and 16.6 cm?1, respectively. Using linear correlations instead of scaling factors improves the prediction accuracy significantly for all functionals. Experimental and computed spectra for a single complex can show significant differences even when the molecular structure is calculated correctly, and a means of defining confidence limits for any given computed structure is also provided.

PH-Dependence of Binding Constants and Desorption Rates of Phosphonate- and Hydroxamate-Anchored [Ru(bpy)3]2+ on TiO2 and WO3

The binding constants and rate constants for desorption of the modified molecular dye [Ru(bpy)3]2+ anchored by either phosphonate or hydroxamate on the bipyridine ligand to anatase TiO2 and WO3 have been measured. In aqueous media at pH 1-10, repulsive electrostatic interactions between the negatively charged anchor and the negatively charged surface govern phosphonate desorption under neutral and basic conditions for TiO2 anatase due to the high acidity of phosphonic acid (pKa,4 = 5.1). In contrast, the lower acidity of hydroxamate (pKa,1 = 6.5, pKa,2 = 9.1) leads to little change in adsorption/desorption properties as a function of pH from 1 to 7. The binding constant for hydroxamate is 103 in water, independent of pH in this range. These results are true for WO3 as well, but are not reported at pH > 4 due to its Arrhenius acidity. Kinetics for desorption as a function of pH are reported, with a proposed mechanism for phosphonate desorption at high pH being the electrostatic repulsion of negative charges between the surface and the anionic anchor. Further, the hydroxamic acid anchor itself is likely the site of quasi-reversible redox activity in [Ru(bpy)2(2,2?-bpy-4,4?-(C(O)N(OH))2)]2+, which does not lead to any measurable deterioration of the complex within 2 h of dark cyclic voltammogram scans in aqueous media. These results posit phosphonate as the preferred anchoring group under acidic conditions and hydroxamate for neutral/basic conditions.

Synthesis and photophysics of ruthenium(II) complexes with multiple pyrenylethynylene subunits

We describe the synthesis and photophysical properties of new Ru(II) complexes bearing different numbers of pyrenylethynylene substituents in either the 5 or 5,5? positions of 2,2?-bipyridine. Static and dynamic absorption and luminescence measurements reveal the nature of the lowest excited states in each molecule. The 5-substituted complexes display behavior dominated by triplet intraligand pi,pi* excited states, generating long-lived room temperature phosphorescence in the red. While the photophysical properties in the 5,5?-substituted case are still largely influenced by triplet intraligand pi,pi* excited states, the data suggest the possibility of an excited state manifold composed of “mixed” intraligand and charge transfer character.
