Photoelectrochemical behavior of multimetallic assemblies based on [Ru(bpy)3]2+-terpyridine building block: [Ru(II)–M–Ru(II)]n+ in solution and [Ru(II)–M]n+ dyad anchored on ITO (M=Co(III), Fe(II))

One of the bipyridines of a [Ru(bpy)3]2+ core has been substituted at its 5 position by a terpyridine chelating unit through an ether bridge. The modification has only a minor influence on the photophysical and electrochemical properties of the Ru…

A Highly Selective Potassium Sensor for the Detection of Potassium in Living Tissues

The development of highly selective sensors for potassium is of great interest in biology. Two new hydrosoluble potassium sensors (Calix-COU-Alkyne and Calix-COU-Am) based on a calix[4]arene bis(crown-6) and an extended coumarin were synthesized and…

Kinetic study of azobenzene E/Z isomerization using ion mobility-mass spectrometry

IntroductionAzobenzene molecular switches can interconvert both photochemically and thermally. Due to their important development, their fast identification has become a challenge. Usually identified using UV-VIS spectrophotometry, we propose…

Rapid Prototyping of Chemical Microsensors Based on Molecularly Imprinted Polymers Synthesized by Two-Photon Stereolithography

Two-photon stereolithography is used for rapid prototyping of submicrometre molecularly imprinted polymer-based 3D structures. The structures are evaluated as chemical sensing elements and their specific recognition properties for target molecules…

Linear and non-linear optical spectroscopy of 'well-behaved' colloidal suspensions of nanocrystal assemblies

The directed self-assembly of nanocrystals in the liquid phase can yield new materials with interesting optical properties for potential applications in medical diagnostics, phototherapy, photoenergy, and the guiding of light. Development of self…

Optical extinction and scattering cross sections of plasmonic nanoparticle dimers in aqueous suspension

Absolute extinction and scattering cross sections for gold nanoparticle dimers were determined experimentally using a chemometric approach involving singular-value decomposition of the extinction and scattering spectra of slowly aggregating gold…
