Abstract

A series of substituted phenylene ethynylene diazonium salts were prepared from the corresponding anilines by the action of nitrosonium tetrafluoroborate in sulfolane-acetonitrile solvent. Formation of self-assembled layers of the diazonium salts in acetonitrile solution was demonstrated on Au, Cu and Pt surfaces. The self-assembly rate of the diazonium salts was found to be markedly dependent on the electron withdrawing character of the substituents attached to the aromatic rings.

8. To maximize the solubility of the starting amines, a mixture of sulfolane with only 10- 25% acetonitrile was used for their dissolution, while the nitrosonium tetrafluoroborate was suspended in a lower freezing mixture of sulfolane with 75-90% acetonitrile.Google Scholar

10. CAUTION! All dry diazonium salts reported in this study displayed considerable DSC exotherms above 100-120°C and should be handled as potentially explosive materials. Oligo(phenylene ethynylene)diazonium tetrafluoroborates are moderately light sensitive and should be stored in a freezer in the dark to avoid decomposition.Google Scholar
