Phenomenally High Molar Extinction Coefficient Sensitizer with "Donor- Acceptor” Ligands for Dye-Sensitized Solar Cell Applications

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jun Ho Yum, Robin Humphry-Baker

A phenomenally high molar extinction coefﬁcient heteroleptic ruthenium(II) complex [Ru(4,4′-carboxylic acid-2,2′- bipyridine)(4,4′-(4-{4-methyl-2,5-bis[3-methylbutoxy]styryl}-2,5-bis[3- methylbutoxy]-2,2′-bipyridine)(NCS)2] (DCSC13) was synthesized by inco ...

Luminescent coordination nanoparticles

Water-soluble lanthanide-containing coordination nanoparticles with a size around 4-5 nm were prepared by the growth confinement of the Tb-2(bdc)(3)(H2O)(4) three-dimensional network using an organic polymer; the terbium- and the europium-based objects pre ...

Ruthenium nanoparticles intercalated in hectorite: A reusable hydrogenation catalyst for benzene and toluene

Gabor Laurenczy, André Meister

The cationic organometallic aqua complexes formed by hydrolysis of [(C 6H6)RuCl2]2 in water, mainly [(C6H6)Ru(H2O)3]2+, intercalate into sodium hectorite by ion exchange, replacing the sodium cations between the anionic silicate layers. The yellow hectorit ...

Development of Ruthenium Antitumor Drugs that Overcome Multidrug Resistance Mechanisms

Paul Joseph Dyson, Wee Han Ang, Andrew Douglas Phillips, Claudine Scolaro, Gianni Sava

Organometallic ruthenium(II) complexes of the general formula [Ru(η6-p-cymene)Cl2(L)] and [Ru(η6-p-cymene)Cl(L)2][BPh4] with modified phenoxazine- and anthracene-based multidrug resistanc ...

Structure-activity relationships for ruthenium(II)-arene drugs

Claudine Scolaro

The discovery of the anticancer properties of cisplatin in 1965 heralded the development of metallopharmaceuticals and founded a revolution in cancer therapy. Platinum drugs are believed to induce cytotoxicity by cross-linking DNA, causing changes to the D ...

Investigation of atomic-layer-deposited ruthenium nanocrystal growth on SiO2 and Al2O3 films

Wei Chen, Min Zhang

The growth of ruthenium (Ru) nanocrystals on the SiO2 and Al2O3 films has been investigated using atomic layer deposition (ALD) method, indicating that much higher density Ru nanocrystals are grown on the Al2O3 film compared with the SiO2 film. Ru nanocrys ...
