A Mesoionic Diselenolene Anion and the Corresponding Radical Dianion

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Andrzej Sienkiewicz, Abdusalom Suleymanov, Zhaowen Dong, Cesare Berton

Dichalcogenolenes are archetypal redox non-innocent ligands with numerous applications. Herein, we describe a diselenolene ligand with fundamentally different electronic properties. By selenation of a C2-protected imidazolium salt, we have prepared a mesoi ...

Cyclometalated Ruthenium Complexes for Dye-Sensitized Solar Cells

Sadig Aghazada

The transition towards carbon-free sources of energy is vital for humankind. This process is feasible through the extensive use of photovoltaic technologies, which may convert solar energy into elec-trical and chemical energy. In the last half-century, man ...

Investigation of Key Parameters Affecting Ion-Capturing Abilities of Mixed-Ligand Protected Gold Nanoparticles

Elif Ertem Bekdemir

Over the past decades, there has been a dramatic change in the types and amounts of metal ions in the biosphere, since we have introduced huge amount of metal waste into our environment in the course of industrialization of our society. Most of the metal c ...

Modulating protein activity using tethered ligands with mutually exclusive binding sites

Kai Johnsson, Rudolf Griss, Alberto Schena

The possibility to design proteins whose activities can be switched on and off by unrelated effector molecules would enable applications in various research areas, ranging from biosensing to synthetic biology. We describe here a general method to modulate ...

Reactivity and Biological Properties of a Series of Cytotoxic PtI2(amine)(2) Complexes, Either cis or trans Configured

Angela Casini

Six diiodido-diamine platinum(II) complexes, either cis or trans configured, were prepared, differing only in the nature of the amine ligand (isopropylamine, dimethylamine, or methylamine), and their antiproliferative properties were evaluated against a pa ...

Dynamic Cellular Uptake of Mixed-Monolayer Protected Nanoparticles

Francesco Stellacci, Randy Patrick Carney, Tamara Michael Carney, Marie Mueller

Nanoparticles (NPs) are gaining increasing attention for potential application in medicine; consequently, studying their interaction with cells is of central importance. We found that both ligand arrangement and composition on gold nanoparticles play a cru ...

A new familiy of heteroleptic ruthenium(II) polypyridyl complexes for sensitization of nanocrystalline TiO2 films

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jun Ho Yum, Takeru Bessho

Two new heteroleptic ruthenium(II) photosensitizers that contains 2,2';6,2 ''-terpyridine with extended p-conjugation with donor groups, a 4,4'-dicarboxylic acid-2,2'-bipyridine anchoring ligand and a thiocyanate ligand have been designed, synthesized and ...

Isomerization mechanisms of a labile Co(II) octahedral complex

André Merbach, Lothar Helm, Fabrice Riblet

The labile cobalt (II) complex [Co(TUF)2(Pic)2] with 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedione (TUF) bidentate and 4-methylpyridine (Pic) monodentate ligands was studied by variable temp. (VT) 19F NMR from 184 to 312 K. In contrast to the solid state, ...
