Synthesis of monodisperse oligo-p-phenylenes via rhodium-catalyzed alkyne cyclotrimerization.
[structure: see text] A novel synthesis of monodisperse oligo-p-phenylenes is described that features alkyne cyclotrimerization of ether-linked p-dialkynylarenes. This route introduces solubilizing dihydrofuran and alcohol functional groups that may improve processing of the corresponding polymeric p-phenylene materials.
