“…Supramolecular nanocapsule 1 provides a spherical cavity protected by eight anthracene panels (Fig. 1b) [24][25][26] . The capsule assembles from two Pd(II) ions and four bent bispyridine ligands 2 with two embedded anthracene rings in a quantitative yield and encapsulates neutral guest molecules with the size up to 1 nm, in which the guests are shaded from the outside by the closed polyaromatic shell.…”

“…2a) with two embedded anthracene panels to design molecular tube 1. The rigidly bent conformation of 2b facilitates the formation of supramolecular assemblies such as (i) capsular structures through noncovalent, coordinative transition-metal linkages [18][19][20][21] and (ii) bowlshaped structures through covalent methylene linkages 22,23 . For the preparation of the tubular structure, we employed Zincke reaction 24,25 to form two phenyl-pyridyl bonds on 1 without using a transition-metal catalyst.…”

Long hydrocarbon chains are essential components of biomolecules used for structure and function in living organisms. The selective recognition and effective binding of hydrocarbons within synthetic host compounds are problematic owing to their conformational flexibility and the lack of specific binding sites. Here we report a molecular tube with polyaromatic frameworks prepared by the Zincke cross-coupling reaction. The tube has a well-defined cylindrical cavity with a diameter and length of B1 nm encircled by multiple anthracene panels and thereby binds long hydrocarbons containing branched methyl groups and/or unsaturated carbon-carbon double bonds (for example, heptamethylnonane, nervonic acid ester and squalene) with high selectivity in aqueous solutions.
