“…In Figure c compared with Figure a, the appearance of a sharp band peaking at 1098 cm −1 indicates that at least partial O atoms of P═O are coordinated with Eu 3+ of the complex, which can also be confirmed by the UV‐Vis absorption spectra shown in Figure S2. The absorption bands at 222 and 283 nm are assigned to the absorption of imidazole ring of IL and oxazoline ring of pybox ligand, respectively, revealing the modification of the IL on Eu(pybox) 3 . It is worth noting that the IL can not only improve the luminescent behavior of the complex but also enhance the thermal stability of PMMA film, which will be discussed in detail in the following parts.…”

Ionic liquid (IL)‐based lanthanide luminescent materials with luminescent downshifting properties are beneficial for enhancing the photovoltaic energy conversion efficiency (ηpv) of silicon‐based solar cells. Herein, novel lanthanide (III) complex‐doped ILs have been successfully prepared by simply dissolving the complex Ln(pybox)3 (Ln = Eu or Tb, pybox = 2,6‐bis[(4R)‐4‐phenyl‐2‐oxazolinyl]pyridine) into a bidentate organophosphine functionalized IL (1,3‐bis‐[3‐(diphenylphosphinyl)propyl]imidazolebis (trifluoromethylsulfonyl)imide), showing improved luminescence efficiency attributed to the coordination of ILs with Ln3+ ions and thus occurrence of the energy transfer from ILs to Ln3+ ions and very high absolute quantum efficiency (up to 97.22%). Large area (17 × 17 cm2) flexible, transparent, and luminescent poly(methyl methacrylate) thin films were prepared through a simple drop‐casting method and were applied as luminescent downshifting coatings to the silicon‐based heterojunction solar cells (active area: 235 cm2). In the best case using the Tb3+‐containing film, the ηpv of the solar cell increases from 16.676 to 16.774%.

“…In an earlier report, the complex [Ru(bpy) 2 (py)O] 2+ was employed in the stereoselective oxidation of sulfides to sulfoxides . The stereoselectivity observed is disappointing but is comparable to that found with the complex [Ru(( S )-bpop)(trpy)O] 2+ where ( S )-bpop is the chiral ligand 2,2-bis[2-[4( S )-phenyl-1,3-oxazolinyl]]propane …”

The chiral oxazoline complexes cis- and trans-[Ru((SS)-Pr(i)pybox)(py)(2)Cl]PF(6) were prepared from the common precursor trans-[Ru((SS)-Pr(i)pybox)(py)Cl(2)], and all three complexes were spectroscopically and structurally characterized. The complex cis-[Ru((SS)-Pr(i)pybox)(py)(2)Cl]PF(6) crystallized in P2(1)2(1)2(1) with Z = 4, a = 8.396(2) Å, b = 18.396(3) Å, c = 20.954(3) Å, and R = 0.039 for 4131 reflections. The complex trans-[Ru((SS)-Pr(i)pybox)(py)(2)Cl]PF(6) crystallized in P2(1) with Z = 2, a = 10.110(2) Å, b = 13.566(2) Å, c = 12.043(2) Å, beta = 106.10(2) degrees, and R = 0.039 for 3869 reflections. The precursor trans-[Ru((SS)-Pr(i)pybox)(py)Cl(2)] crystallized in P2(1)2(1)2(1) with Z = 8, a = 15.856(2) Å, b = 17.216(1) Å, c = 17.768(1) Å, and R = 0.030 for 5826 reflections. A related reagent, [Ru((SS)-Pr(i)pybox)(bpy)Cl]PF(6), was prepared by a more direct route and was also characterized. Aqua complexes were formed by hydrolysis of the chloride ligand in the bis(pyridine) complexes with retention of the stereochemistry. Electrochemical oxidation of the aqua complexes yielded oxo species which are formally ruthenium(IV). Reactions of the oxo complexes with the prochiral reductant, methyl p-tolyl sulfide led to stereoselective formation of the sulfoxide with enantiomeric excess of the R isomer ranging from 7% to 13%.

“…Another system is described in ref. 79. In this case chirality is introduced by a 2,2-bis[2-(4(S)-or 4(R)-phenyl-l,3-oxazolinyl)]propane that was coordinated together with unfunctionalized terpyridine to an oxo-ruthenium(IV) complex.…”

Recent developments in the supramolecular chemistry of terpyridine–metal complexes

2004

View full text Add to dashboard Cite

This critical review describes recent developments in the field of supramolecular chemistry of terpyridine-metal complexes. The synthesis and characteristics of single as well as multiple homo- and heterometallic complexes is discussed. Furthermore, complexes containing fullerenes, biological building blocks, extended aggregates of different architectures as well as rings are presented. A special emphasis is placed upon the properties (e.g. redox properties, luminescence etc.) of functional systems. Potential applications in optical nano-devices, molecular storage units, molecular switches and solar cells are discussed.
