The usefulness of rigid-rod p-octiphenyls with the novel 1²,2²,3³,4²,5³,6²,7³,8²-motif as staves in rigid-rod β-barrel pores is evaluated. Comparison with the known characteristics of isomeric pores with the common 1³,2³,3²,4³,5²,6³,7²,8³-sequence indicates that the self-assembly and the supramolecular chirality of rigid-rod β-barrels are independent of the substitution pattern of the p-octiphenyl stave. NMR tags added at the rod termini are shown to facilitate product characterization.
