| Abstract: | Introduction Recently, much attention has been paid to monodisperse, well-defined conjugated oligomers as candidates for molecular wires and molecular scale electronic devices[1-7]. Shape persistent oligo(1,4-phenyleneethynylene)s are especially attractive for their excellent main-chain rigidity and interesting electronic characteristics[3-7]. Different iterative divergent/convergent routes have been reported by several groups for the rapid synthesis of oligo(1,4-phenyleneethynylene)s. Godt et al.[5] |
