Publisher Correction: Porous covalent organic nanotubes and their assembly in loops and toroids

Abstract

In the version of this Article originally published, there was an error in the structure of compound 31 in Table 1 (and pages 25, 158, 159 of the Supplementary Information) and in the structure of compound 58 in Fig. 3 (and pages 41, 252, 253 of the Supplementary Information). In the original version, the nitrogen and sulfur atoms in the benzoisothiazole ring present in each structure were the wrong way around. This has now been corrected.
