Abstract
- A facile synthetic method involving S<SUB>N</SUB>Ar coupling of 4-fluoronitrobenzene to arylamines, followed by reduction of the nitro groups, has been developed. The method allows the preparation of symmetric (NH<SUB>2</SUB>/NH<SUB>2</SUB> end-capped) and asymmetric (Ph/NH<SUB>2</SUB> end-capped) oligoanilines of even or odd chain lengths. The preparation of the NH<SUB>2</SUB>/NH<SUB>2</SUB> end-capped trimer to octamer and Ph/NH<SUB>2</SUB> end-capped trimer to pentamer is described. The effect of the chain length on the spectroscopic properties of the oxidized oligomers has been investigated by UV-Vis-NIR spectroscopy.
