INCLUSION OF WATER BY A CROWN AMIDE - 1ST CRYSTAL-STRUCTURE OF A RESPECTIVE HOST-GUEST COMBINATION
Synthesis of 2,2'-bipyridines : from versatile building blocks to sexy architectures and functional (nano)materials
The latest synthetic strategies to prepare 2,2-bipyridine and its mono-substituted, symmetrical and unsymmetrical 3,3-, 4,4-, 5,5-, and 6,6-disubstituted derivatives are critically discussed and evaluated. Different coupling procedures to achieve new symmetrical and unsymmetrical functionalized 2,2-bipyridines, such as Stille-type, Negishi-type, and Suzuki-type cross-coupling reactions are discussed in detail. Moreover, condensation procedures that allow further variations are presented. The application of functional group transformations for access to additional groups is examined
Electrochemical and spectrophotometric properties of polymers based on derivatives of di- and triphenylamines as promising materials for electronic applications

“Vapoconductivity”. Sorption of organic vapors causes large increases in the conductivity of a dendrimer
International audienceDendrimers peripherally modified with oligothiophene cation radicals were prepared. The electrical conductivity of thin films showed rapid, dramatic (up to 800x), and reversible increases in conductivity when exposed to certain organic vapors
