Sensitization of the NIR emission of Nd(III) by the 4a atropoisomer of a mesotetraphenyl porphyrin bearing four 8-hydroxyquinolinylamide chelates
For many optical devices such as for example amplifiers and lasers, the luminescence properties of lanthanide ions are of particular interest. Indeed, lanthanide ions emit narrow bands ranging from visible to near–infrared. However, owing to the low absorption coefficients of Laporte-forbidden ...

Junctions between carbon nanotubes and metal crystals
A way of creating junctions between nanometer-sized metal crystals and carbon nanotubes was discovered by an international research team, led by researchers at the Institut de Physique et Chimie des Matériaux in Strasbourg. The development of a technique for establishing strong covalent bonds ...

Supramolecular Glassy and Crystalline Nanoporous 2D Networks
Supramolecular engineering comprises the design, synthesis and self-assembly of well-defined molecular modules into tailor-made architectures. Towards this end, control over the self-recognition and self-assembly processes are milestones in engineering functional materials. Particularly, self-assembly ...

Liquid-crystalline Single Molecule Magnets
Single Molecule Magnets (the archetype of which is the so-called "Mn12", a polymetallic Mn complex, of formula [Mn12O12(OAc)16(H2O)4]) have the remarkable property of showing an extremely slow relaxation of their magnetization below a blocking temperature (D. Gatteschi, R. Sessoli, Angew. ...
