(Chemical Equation Presented) A series of unsymmetrical bi- and tetrathiophenes have been synthesized with bipyridine and phosphonic acid functional groups. To do this, phosphonic esters were bonded to thiophenes and the thiophenes coupled to bipyridine. After synthesis of the thienylbipyridines, bis(bipyridine) ruthenium was coordinated to them through the bipyridines. The thienylbipyridines absorb visible light and fluoresce; however, on attachment to ruthenium, both their fluorescence and that of ruthenium are quenched. An additional effect of coordinating ruthenium to the thiophenes is a new absorption band around 470 nm. Variation in oligothiophene length and bipyridine substitution position allowed comparison of the effect of these variables on electronic properties. The longer oligothiophenes display lower-energy absorptions and emissions than that of the shorter thiophenes. In contrast, the position of the bipyridine attachment does not have a large effect on the absorbance or emission wavelength, or on the fluorescence quantum yield.

Abstract: 3-(2,2?-Bipyridine-4-yl)-2-propenoic acid ethyl ester which may be used for the introduction of metal coordination sites in polyacrylates is synthesized by an improved synthetic route to the key intermediate 4-bromo-2,2?-bipyridine working under microwave conditions, which leads to drastic shortening of reaction times, as well as to the reduction of reaction steps. In addition, a synthetic procedure to formyl-bipyridines that is not based on reductive or oxidative reaction conditions could be applied. Starting from the formyl-bipyridine derivative the title compound may be effectively generated using modified Horner?Wadsworth?Emmons reaction conditions to yield the new ligand.

Suzuki-Miyauru cross-coupling of bromopolypyridines with potassium vinyltrifluoroborate affords vinyl-substituted polypyridyl ligands in moderate to good yields. This reaction allows simple and practical syntheses of numerous vinyl-substituted polypyridines, such as 4?-vinyl-2,2?:6?, 2?-terpyridine, 5,5?-divinyl-2,2?-bipyridine, and 4,4?-divinyl-2,2?-bipyridine. In addition, a new ruthenium complex, [Ru(5,5?-divinyl-2,2?-bipyridine)3]2+, was synthesized and found to undergo reductive electropolymerization smoothly.

A simple and flexible synthesis for a series of star-shaped pyridine, bipyridine, and terpyridine derivatives is reported by using a modular approach that combines the use of a ligand, spacer, and core unit. A fairly efficient method to prepare 4?-nonafloxy-functionalized terpyridine derivatives is described. The building blocks that contain the functionalized pyridine, bipyridine, or terpyridine derivatives were linked to different C3-symmetrical core units. In most cases, Sonogashira reactions were employed in the crucial final steps of the synthesis. A star-shaped dodecafluorinated compound was also prepared in a straightforward fashion. A simple procedure for the preparation of partially silylated 1,3,5-triethynylbenzene derivatives is presented, which provides an approach to C2-symmetrical star-shaped compounds that have only one terpyridine and two terphenyl units as “dummy” ligands. The absorption and emission spectra of the fully conjugated C3-symmetrical pyridine derivatives were systematically investigated, and fairly large Stokes shifts were observed.

In order to apply boronic acid-saccharide interactions to the chiroselective synthesis of Delta- and Lambda-[CoIII(bpy)3]3+ saccharide-binding ligands, 2,2?-bipyridine-4-boronic acid (bpymb) and 2,2?-bipyridine-4,4?-diboronic acid (bpydb) were newly synthesized. It was shown that most D-saccharides form cyclic 1:1 complexes with bpydb to afford the CD-active species. The positive exciton coupling band implies that two pyridine rings are twisted in a clockwise direction ((R)-chirality). In contrast, such a CD-active species was not yielded from bpymb. The treatment of the bpydb-D-saccharide complexes with Co(OAc)2 gave the substitution-active [CoII(bpyba)3]4–saccharide complexes, which were oxidized to the substitution-inactive [CoIII(bpyba)3]3–saccharide complexes. In this stage, the Delta vs. Lambda ratio was fixed. The complexes were converted to [CoIII(bpy)]3+ by treatment with AgNO3 and the e.e. was determined by comparison with authentic Delta- or Lambda-[CoIII(bpy)]3+. The Delta-isomer was obtained in excess from most D-saccharides but the Lambda-isomer was also obtained from D-fructose and D-fucose. At 4C, the largest e.e. for bpydb was attained with D-glucose (47% e.e.; Delta excess). Under the same reaction conditions the bpymb + D-glucose system gave 16% e.e. (Delta excess). The e.e. of the bpydb + D-glucose system increased with lowering the reaction temperature and at -25C it reached 79% e.e. The foregoing results clearly establish that the saccharide-templated synthesis is useful as a new concept for the preparation of chiral tris(2,2?-bipyridine)-metal complexes. Furthermore, the Delta vs. Lambda equilibrium can be shifted in either direction by the selection of saccharide enantiomers.

A major goal of artificial photosynthesis research is photosensitizing highly reducing metal centers using as much as possible of the solar spectrum reaching Earth’s surface. The radical anions and dianions of rylenediimide (RDI) dyes, which absorb at wavelengths as long as 950 nm, are powerful photoreductants with excited state oxidation potentials that rival or exceed those of organometallic chromophores. These dyes have been previously incorporated into all-organic donor-acceptor systems, but have not yet been shown to reduce organometallic centers. This study describes a set of dyads in which perylenediimide (PDI) or naphthalenediimide (NDI) chromophores are attached to Re(bpy)(CO)3 through either the bipyridine ligand or more directly to the Re center via a pyridine ligand. The chromophores are reduced with a mild reducing agent, after which excitation with long-wavelength red or near-infrared light leads to reduction of the Re complex. The kinetics of electron transfer from the photoexcited anions to the Re complex are monitored using transient visible/near-IR and mid-IR spectroscopy, complemented by theoretical spectroscopic assignments. The photo-driven charge shift from the reduced PDI or NDI to the complex occurs in picoseconds regardless of whether PDI or NDI is attached to the bipyridine or to the Re center, but back electron transfer is found to be three orders of magnitude slower with the chromophore attached to the Re center. These results will inform the design of future catalytic systems that incorporate RDI anions as chromophores.

Ag+-free complexation of alkyne-bipyridines at ruthenium(II) polypyridine centers proceeds with surprisingly low yields. The alkyne-bipyridine-substituted ruthenium(II) polypyridine complexes in this work were characterized by NMR spectroscopy, ESI spectrometry, and single-crystal X-ray structural analysis. A detailed analysis of the side products revealed an unexpected carbon-carbon alkyne bond splitting promoted by the ruthenium(II) center, leading to the formation of a CO-RuII species, methyl-bipyridine, and a methyl-bipyridine-substituted ruthenium(II) complex accompanying the target product. The side products were characterized using complimentary methods including X-ray crystallography. A possible mechanism is suggested based on these side products and exemplary reaction studies. For the coordination reaction of alkyne-bipyridines with Ru(bpy)2Cl2 unexpected side reactions take place, forming a RuII-CO species and methyl-bipyridine. Here we give a detailed mechanism of the side reactions and an adequate workup procedure to obtain a pure alkyne-substituted ruthenium(II) polypyridine complex, which is the intended product.

A series of bipyridyl-Pd and Rh complexes containing a [(bpy) 3Ru]2+ or [(bpy)2Ru(phen)]2+ (bpy = 2,2?-bipyridyl, phen = 1,10-phenanthroline) moiety as visible-light absorbing unit was synthesized. The complexes were synthesized via a Suzuki-Miyaura coupling reaction between the Ru complexes having a 4-bromo-2,2?-bipyridyl ligand and a 2,2?-bipyridyl-4-boronic acid and a subsequent reaction with various mononuclear Pd and Rh precursors. There was a noticeable structural difference between the QP (2,2?:4?, 4?:2?,2?-quaterpyridyne) and PB (5-(2,2?-bipyridyl)-yl- 1,10-phenanthroline) complexes, which involved the dihedral angles within the bridging ligand; the PB complexes possessed large dihedral angles but the QP complexes showed small values. This structural difference clearly indicated a strong pi-conjugation through the QP ligand. The electrochemical and photophysical properties of the QP and PB complexes were compared with the parent mononuclear Ru complexes, such as [(bpy)3Ru]2+, [(bpy)2Ru(phen)]2+, and [(bpy)2Ru(bpm)] 2+ (bpm = 2,2?-bipyrimidine). The QP and PB complexes showed a 3MLCT life time that was similar to [(bpy)3Ru] 2+ and [(bpy)2Ru(phen)]2+, which was about 10 times longer (ca. 1 mus) than the corresponding bpm complexes. Reactivity studies with Pd complexes toward styrene dimerizations were examined. The reaction proceeded under visible-light irradiated conditions and the reactivity of the QP complexes was much higher than the corresponding PB complexes. Substantial acceleration of the reaction was observed with the introduction of an Me substituent on the bipyridyl ligand.

In this Communication, we present the synthesis and use of [Ru(bpy) 2(bpy-CCH)]2+, a versatile synthon for the construction of more sophisticated dyads by means of click chemistry. The resulting chromophore-acceptor or -donor complexes have been studied by flash photolysis and are shown to undergo efficient electron transfer to/from the chromophore. Additionally, the photophysical and chemical properties of the original chromophore remain intact, making it a very useful component for the preparation of visible-light-active dyads.
