A Cu-catalyzed benzannulation reaction transforms <i>ortho</i>(arylene ethynylene) oligomers into <i>ortho</i>-arylenes. This approach circumvents iterative Suzuki cross-coupling reactions previously used to assemble hindered <i>ortho</i>-arylene backbones. These derivatives form helical folded structures in the solid-state and in solution, as demonstrated by X-ray crystallography and solution-state NMR analysis. DFT calculations of misfolded conformations are correlated with variable-temperatur ...[more]
