| Résumé |
|
An oligophenylene deriving from the 4-(methoxyphenyl)acetonitrile (MPA), was electrosynthesized by direct anodic oxidation at a constant potential in acetonitrile on a platinium electrode. This oligomer (OMPA) showed a good solubility in common organic solvents. The results of osmometry and gel permeation chromatography analyzes indicated that the average chain length for OMPA was about 5 units. Its chemical structure was elucidated by H-1 and C-13 NMR, FTIR and UV spectroscopy. A thermal study carried out by thermogravimetric analysis and Differential Scanning Calorimetry showed that the oligomer was stable up to 268 degrees C. In addition, the photoluminescent properties of OMPA were investigated. In solution, an emission was recorded in the indigo-blue region, however, in solid state this emission was shifted to the orange red zone. Finally a mechanism for the electro-oligomerization was evoked in the light of the electronic structures of the MPA and its radical cation obtained by DFT calculation. (C) 2012 Elsevier B.V.
