Hybrid systems prepared by fixing a Re(I) complex and a dye on three types of TiO2 nanoparticles in two different ways commonly revealed persistent photocatalysis of the CO2 reduction to CO with no leveling-off tendency under visible-light irradiation in DMF, giving a turnover number of ≥435.

HPLC of Formula: 138219-98-4On November 25, 2013 ,《Structure-Activity Relationships and Identification of Optmized CC-Chemokine Receptor CCR1, 5, and 8 Metal-Ion Chelators》 appeared in Journal of Chemical Information and Modeling. The author of the article were Chalikiopoulos, Alexander; Thiele, Stefanie; Malmgaard-Clausen, Mikkel; Rydberg, Patrik; Isberg, Vignir; Ulven, Trond; Frimurer, Thomas M.; Rosenkilde, Mette M.; Gloriam, David E.. The article conveys some information:

Chemokine receptors are involved in trafficking of leukocytes and represent targets for autoimmune conditions, inflammatory diseases, viral infections, and cancer. We recently published CCR1, CCR8, and CCR5 agonists and pos. modulators based on a three metal-ion chelator series: 2,2′-bipyridine, 1,10-phenanthroline, and 2,2′;6′,2”-terpyridine. Here, we have performed an in-depth structure-activity relationship study and tested eight new optimized analogs. Using d. functional theory calculations we demonstrate that the chelator zinc affinities depend on how electron-donating and -withdrawing substituents modulate the partial charges of chelating nitrogens. The zinc affinity was found to constitute the major factor for receptor potency, although the activity of some chelators deviate suggesting favorable or unfavorable interactions. Hydrophobic and halogen substituents are generally better accommodated in the receptors than polar groups. The new analog brominated terpyridine (29) resulted in the highest chelator potencies observed so far CCR1 (EC50: 0.49 μM) and CCR8 (EC50: 0.28 μM). Furthermore, we identified the first selective CCR5 agonist chelator, meta dithiomethylated bipyridine (23). The structure-activity relationships contribute to small-mol. drug development, and the novel chelators constitute valuable tools for studies of structural mechanisms for chemokine receptor activation. The results came from multiple reactions, including the reaction of 4,4′-Bis(chloromethyl)-2,2′-bipyridine(cas: 138219-98-4HPLC of Formula: 138219-98-4)

4,4′-Bis(chloromethyl)-2,2′-bipyridine(cas: 138219-98-4) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized.

《Synthesis, characterization and introduction of a new ion-coordinating ruthenium sensitizer dye in quasi-solid state TiO2 solar cells》 was published in Journal of Photochemistry and Photobiology, A: Chemistry in 2011. These research results belong to White, Ryan C.; Benedetti, Joao E.; Goncalves, Agnaldo D.; Romao, Wanderson; Vaz, Boniek G.; Eberlin, Marcos N.; Correia, Carlos R. D.; De Paoli, Marco A.; Nogueira, Ana F.. Application of 138219-98-4 The article mentions the following:

A new ion-coordinating heteroleptic ruthenium(II) dye was synthesized by attaching two crown ether moieties in the 4,4′ positions of one of the bipyridine ligands. This new dye (named as RC730) was characterized by UV-Vis spectroscopy, CHN elemental anal., NMR and electrospray ionization Fourier transform-ion cyclotron resonance mass spectrometry (ESI FT-ICR MS). In order to investigate the properties of these ion-coordinating species, dye-sensitized solar cells were assembled with a gel polymer electrolyte based on two different cations: lithium and sodium. The devices were characterized by J-V curves under 100 mW cm-2, incident photon to current conversion efficiency spectra (IPCE) and photovoltage decay transients under open-circuit conditions. The solar cells based on the new heteroleptic dye provided higher photocurrent and photovoltage when lithium was used in the electrolyte instead of sodium cations, reaching overall conversion efficiencies up to 2%. This behavior might be related to the ability of the ion-coordinating RC730 dye to trap Li ions, minimizing the conduction band edge shift. When the polymer electrolyte based on lithium is used, the IPCE spectra show a maximum efficiency of 31% at the maximum absorption peak of the RC730 dye (ca. 530 nm).
