Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

A dynamic combinatorial library of metal–dye complexes was obtained by reacting aqueous solutions of the dyes Methyl Calcein Blue, Arsenazo I, and Xylenol Orange with CuCl2 and NiCl2. The mixture gave a characteristic UV-Vis response upon addition of the p ...

A mixture of the Pd(II) complex [Pd(NO3)2(bipy)] (bipy = 2,2-bipyridine) and the fluorescent dye Methylcalcein blue (MCB) constitutes a chemosensing ensemble which can be used for the detection of pyrophosphate (PPi) by fluorescence spectroscopy. The senso ...

Ruthenium complexes with bridging dicarboxylate ligands were combined with 1,2-di-4-pyridylethylene (dpe), 2,4,6-tri-4-pyridyltriazine (4-tpt), or 2,4,6-tri-3-pyridyltriazine (3-tpt) to give a tetranuclear rectangle or hexanuclear coordination cages. The c ...

Ru-built cube: By combining metallasupramolecular chemistry with dynamic covalent chemistry, complex nanostructures can be formed. Large cages are synthesized by reaction of trinuclear metallamacrocycles containing pendant aldehyde groups. ...

Caught in a trap! Fluorimetric chloride sensing in water is achieved by exploiting the changes in partition constant of a receptor complex in its bound and nonbound states. In the presence of chloride, the complex preferentially resides in the micelle pseu ...

The multicomponent reaction of diboronic acids with a catechol and a tripyridyl linker results in the formation trigonal prismatic cages. The cages feature six dative boron–nitrogen bonds as structure-directing elements. The size of the cages can be varied ...
