All rights reserved.Supramolecular biochemistry in confined space made out of macrocyclic particles has attracted much interest, as it can utilize certain binding properties of macrocyclic cavities. Here we report preparation of length-controlled discrete tubular structures by homo-/co-assembly of rim-differentiated and peralkylamino pillar[5]arenes via hydrogen bonds and salt bridges. By dimerization and trimerization, the broadened tubes revealed five-fold helices and st
