Naphthalimide-tagged ruthenium-arene anticancer complexes: combining coordination with intercalation

Paul Joseph Dyson, Catherine Marie Amélie Clavel, Fabio Edafe, Kelly Joan Kilpin

Ruthenium(II) arene compounds have been modified with the naphthalimide group, tethered via the arene ligand, i.e. {dichloroeta(6)-N-(phenylalkyl)(4-dimethylamino)-1,8-naphthalimideruthenium(II)} (alkyl = methyl, ethyl, propyl, pta = 1,3,5-triaza-7- ...

Ruthenium-Catalyzed Sequential Enyne Cross-Metathesis/ATRA Reactions

Kay Severin, Euro Solari, Gregor Kiefer, Jesus Ruiz

Sequential enyne cross-metathesis reactions of arylalkynes with ethylene followed by atom transfer radical addition (ATRA) with ethyl dichloroacetate or dichloroacetonitrile provide 1,5-dichloropent-2-ene derivatives. The second-generation Grubbs alkyliden ...

Catalysts for High Temperature Gas Cleaning in the Production of Synthetic Natural Gas from Biomass

Bio synthetic natural gas (Bio-SNG) is being proposed as an alternative to the natural gas of fossil origin (NG) [1]. Bio-SNG consists mainly of CH4 (at least 95%mol), has a high heating value (e.g. 10 kWh/m3N), and respects the quality standards of the NG ...

Acid-base properties of the N3 ruthenium(II) solar cell sensitizer: a combined experimental and computational analysis

Mohammad Khaja Nazeeruddin, Filippo de Angelis

We report a combined spectro-photometric and computational investigation of the acid-base equilibria of the N3 solar cell sensitizer [Ru(dcbpyH(2))(2)(NCS)(2)] (dcbpyH(2) = 4,4'-dicarboxyl-2,2' bipyridine) in aqueous/ethanol solutions. The absorption spect ...

Influence of cations of the electrolyte on the performance and stability of dye sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Thomas Moehl, Philippe Wyss

The electrolyte is one of the key components for DSC and its properties have great influence on the photo-conversion efficiency and stability of the devices. Five new low volatile electrolytes containing 3-methoxypropionitrile (MPN) as solvent were prepare ...
