Abstract
A novel binuclear complex [(bpy)2Ru(mu-bipp)Ru(bpy)2](ClO4)4, where bpy=2,2'-bipyridine and bipp=2,9-bis(2-imidazo[4,5-f][1,10]phenanthroline)-1,10-phenanthroline has been synthesized. Photophysical results reveal that this complex interacts with calf-thymus DNA with intrinsic binding constant 2.6 x 10(5) M(-1) in the buffer containing 5 mM Tris and 50 mM NaCl. The fact that the intraligand transition of bipp around 370 nm decreased by up to 50% in the presence of DNA, much more pronounced than the metal to ligand charge transfer band around 445 nm indicates the bridging ligand bipp is also the intercalating ligand into DNA base pairs. The emission band around at 601 nm increased by 1.4-fold, and red shifted 14 nm when DNA was added to saturation. The emission quenching of this complex by K4[Fe(CN)6] was depressed greatly when DNA was present. Viscometric measurements also proved the intercalative binding mode.

Abstract
Two new polypyridyl ligands containing substituent Br at different positions in the phenyl ring, PBIP [PBIP=2-(4-bromophenyl)imidazo[4,5-f]1,10-phenanthroline], OBIP [OBIP=2-(2-bromophenyl)imidazo[4,5-f]1,10-phenanthroline] and their Ru(II) complexes, [Ru(phen)2PBIP]2+ 1, [Ru(phen)2OBIP]2+ 2 (phen=1,10-phenanthroline), have been synthesized and characterized. The binding strength of the two complexes to calf thymus DNA (CT DNA) was investigated with spectrophotometric methods, viscosity measurements, as well as equilibrium dialysis and circular dichroism spectroscopy. The theoretical calculations for these two complexes were also carried out applying the density functional theory (DFT) method. The experimental results show that the Br group substituting H at different positions of the phenyl ring in the intercalated ligand has significant effects on the spectral properties and the DNA-binding behaviors of Ru(II) complexes. Both the complexes can bind to CT DNA in intercalative mode and interact with CT DNA enantioselectively. Moreover, complex 1 can bind to CT DNA more strongly than complex 2, and complex 2 can become a much better candidate as an enantioselective binder to CT DNA than complex 1. The theoretical calculations show that both intercalative ligands, PBIP and OBIP, in these two complexes are essentially planar, and the obtained electronic structures of the complexes can be used to explain reasonably some of their experimental regularities or trends. Such experimental and theoretical information will be useful in design of novel probes of nucleic acid structures.

Abstract
New ligand acenaphthereno[1,2-b]-1,4,8,9-tetraazariphenylence (actatp) and its complexes [Ru(bpy)(2)(actatp)](ClO(4))(2).2H(2)O (1) (bpy=2,2'-bipyridine) and [Ru(phen)(2)(actatp)](ClO(4))(2).2H(2)O (2) (phen=1,10-phenanthroline) have been synthesized and characterized by UV-vis, 1H NMR, and mass spectra. The electrochemical behavior of the two complexes was studied by cyclic voltammetry. The interaction of the two complexes with calf thymus DNA has been investigated by spectrophotometric methods and viscosity measurements. The experimental results suggest that both complexes bind to DNA through an intercalative mode. The circular dichroism signals of the dialysates of the racemic complexes against calf thymus DNA are discussed. When irradiated at 302 nm, both complexes have also been found to promote the photocleavage of plasmid pBR 322 DNA.

Abstract
The ligand ODHIP (3,4-dihydroxyl-imidazo[4,5-f][1,10]phenanthroline) and its cobalt(III) complex [Co(bpy)(2)(ODHIP)](3+) were synthesized and characterized. Binding of this complex with calf thymus DNA has been investigated by spectroscopic methods and viscosity. The experimental results indicated that the complex bound to DNA by intercalation. In Tris buffer, the complex could emit relatively weak luminescence. After binding to DNA, the notable enhancement was observed. However, when the Cu(2+) was further added, the luminescence decreased gradually and disappeared after the equimolar concentrations of Cu(2+) was added, which exhibited the "off-on-off" properties of molecular light switch.

Abstract
Four new mixed-ligand complexes, namely [Co(phen)(2)(qdppz)](3+), [Ni(phen)(2)(qdppz)](2+), [Co(phen)(2)(dicnq)](3+) and [Ni(phen)(2)(dicnq)](2+) (phen=1,10-phenanthroline, qdppz=naptho[2,3-a]dipyrido[3,2-H:2',3'-f]phenazine-5,18-dione and dicnq=dicyanodipyrido quinoxaline), were synthesized and characterized by FAB-MS, UV/Vis, IR, 1H NMR, cyclic voltammetry and magnetic susceptibility methods. Absorption and viscometric titration as well as thermal denaturation studies revealed that each of these octahedral complexes is an avid binder of calf-thymus DNA. The apparent binding constants for the dicnq- and qdppz-bearing complexes are in the order of 10(4) and >10(6) M(-1), respectively. Based on the data obtained, an intercalative mode of DNA binding is suggested for these complexes. While both the investigated cobalt(III) complexes and also [Ni(phen)(2)(qdppz)](2+) affected the photocleavage of DNA (supercoiled pBR 322) upon irradiation by 360 nm light, the corresponding dicnq complex of nickel(II) was found to be ineffective under a similar set of experimental conditions. The physico-chemical properties as well as salient features involved in the DNA interactions of the cobalt(III) and nickel(II) complexes investigated here were compared with each other and also with the corresponding properties of the previously reported ruthenium(II) analogues.

Abstract
Multidimensional NMR techniques (1D (1)HNMR, 2D DQF (1)H(1)H COSY and 2D (1)H(1)H NOESY), electrospray ionization mass spectrometry (ESI-MS) and electronic spectroscopy, were performed to study the interactions of the enantiomers lambda- and delta-[Ru(bpy)(2)(HPIP)]Cl(2), (HPIP=2-(2-hydroxyphenyl)imidazo[4,5-f][1,10]phenanthro-line) with the self complementary hexanucleotide duplex d(5'-GTCGAC-3')(2). The results show that the delta-[Ru(bpy)(2)(HPIP)]Cl(2) binds tightly to the oligonucleotide, by intercalation of the ligand HPIP, between the A5 and C6 base sequence of the same strand, probably through the minor groove. Lambda-enantiomer binds weakly, suggesting groove interactions with the hexanucleotide duplex. ESI-MS spectrometry and UV-vis spectroscopy also confirmed these observations.

Abstract
Absorption spectroscopy, fluorescence spectroscopy and viscosity measurements have been used to characterize the DNA binding of [Ru(tpy)(dppt)](2+) (tpy=2,2':6',2"-terpyridine, dppt=3-(1,10-phenanthrolin-2-yl)-5,6-diphenyl-as-triazine), [Ru(tpy)(pta)](2+) (pta=3-(1,10-phenanthrolin-2-yl)-as-triazino[5,6-f]acenaphthylene) and [Ru(tpy)(ptp)](2+) (ptp=3-(1,10-phenanthrolin-2-yl)-as-triazino[5,6-f]-phenanthrene). The results indicate that [Ru(tpy)(pta)](2+) and [Ru(tpy)(ptp)](2+) bind with CT-DNA in an intercalative mode, while [Ru(tpy)(dppt)](2+) binds with DNA by partial intercalation. The ligand planarity of the complex has a significant effect on DNA binding affinity increases in the order [Ru(tpy)(dppt)](2+)<[Ru(tpy)(pta)](2+)<[Ru(tpy)(ptp)](2+).

Abstract
[Ru(bzimpy)(2)]Cl(2), where bzimpy is 2,6-bis(benzimidazol-2-yl) pyridine was synthesized and characterized by ESI-MS, UV-Visible, (1)H NMR and fluorescence spectra. Absorption titration and thermal denaturation experiments indicate that the complex binds to DNA with moderate strength. Viscosity measurement shows that the mode of binding could be surface binding. Fluorescence study shows that the fluorescence intensity of the complex decreases with increasing concentrations of DNA, which is due to the photoelectron transfer from guanine base to (3)MLCT of the complex. Photoexcitation of the complex in the MLCT region in the presence of plasmid DNA has been found to give rise to nicking of DNA.

Abstract
Three hexaaza macrocyclic copper (II) complexes with different functional groups have been synthesized and characterized by elemental analysis and infrared spectra. Absorption and fluorescence spectral, cyclic voltammetric and viscometric studies have been carried out on the interaction of [CuL(1)]Cl(2) (L(1)[double bond]3,10-bis(2-methylpyridine)-1,3,5,8,10,12-hexaazacyclotetradecane), [CuL(2)]Cl(2) (L(2)[double bond]3,10-bis(2-propionitrile)-1,3,5,8,10,12-hexaazacyclotetradecane) and [CuL(3)]Cl(2) (L(3)=3,10-bis(2-hydroxyethyl)-1,3,5,8,10,12-hexaazacyclotetradecane) with calf thymus DNA. The results suggest that three complexes can bind to DNA by different binding modes. The spectroscopic studies together with viscosity experiments and cyclic voltammetry suggest that [CuL(1)](2+) could bind to DNA by partial intercalation via pyridine ring into the base pairs of DNA. [CuL(2)](2+) may bind to DNA by hydrogen bonding and hydrophobic interaction while [CuL(3)](2+) may be by weaker hydrogen bonding. The functional groups on the side chain of macrocycle play a key role in deciding the mode and extent of binding of complexes to DNA. Noticeably, the three complexes have been found to cleave double-strand pUC18 DNA in the presence of 2-mercaptoethanol and H(2)O(2).

Abstract
Studies on the complex [Ru(phen)3]2+ (phen = 1,10-phenanthroline) and its derivatives with 4,7-di-substitution on one ligand(phen) were carried out using the DFT method at the B3LYP/LanL2DZ level of theory. The trends in the substituent effects caused by the electron-pushing group (OH) and the electron-withdrawing group (F), on the electronic structures and the related properties, for example, the energies and the components of some frontier molecular orbitals, the spectroscopy properties, and the net charge populations of some main atoms of the complexes, etc., have been investigated. The computational results show that the substituents have some interesting effects on the electronic structures and the related properties of the complexes. First, according to the analysis of components of LUMO of the complexes, the electron-withdrawing group (F) can activate the main ligand (the substituted ligand, i.e., 2R-phen) and passivate the coligands, on the contrary, the electron-pushing group (OH) can activate the coligands and passivate the main ligand in the first electronic excited states of complexes. Second, both the electron-pushing group (OH) and the electron-withdrawing group (F) can cause a red shift in the electronic ground bands. Third, the characteristics of the atomic net charge populations on the main ligand can also be analyzed in detail by means of a schematic map expressed by several series of arrowheads based on the law of polarity alternation and the idea of polarity interference. The most negative charges are populated on N1, the next most net negative charges are populated on C3 among the skeleton atoms for the three complexes, etc. The computational results can be better used to explain some experimental phenomena and trends.
