                                    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.
                                    该研究评估了具有新型 12,22,33,42,53,62,73,82 位点的刚杆对联辛基苯作为刚杆 β 桶状孔隙中的支柱的实用性。与具有 13,23,32,43,52,63,72,83 共序的异构体孔隙的已知特征进行比较后发现,硬杆 β-桶状孔隙的自组装和超分子手性与对辛基苯基支链的取代模式无关。图中显示了在杆末端添加的 NMR 标记,以方便产品表征。
