A rational approach for the construction of multi-stranded artificial β-sheets based not on hydrogen bonding, but rather on π-π aromatic stacking, is presented. Using 4,6-dinitro-1,3-phenylenediamine units, rigid turns were designed that allow face-to-face π-π interactions between appended linear aromatic segments to be strong enough for folding in an organic solvent, but weak enough to prevent aggregation

the reservoir during the sNT extension, leading to the sNT fission. By comparing the spontaneous and ROFT-mediated entry of AnV into the sNT, we reveal how intricate membrane curvature sensing by small AnV oligomers controls the lattice self-assembly. These results establish sNT-ROFT as a powerful tool for molecular reconstruction and functional analyses of protein oligomerization and self-assembly
