Chain-like assembly of threonine-based cyclophanes through π–π interaction and C–H⋯O hydrogen bond

In this paper, we described the conversion of tube to chain assembly of threonine-based cyclophanes by variation of the steric demand of molecules. The interesting properties of these cyclophanes in hosting hydroxyl-containing guest molecules through three-centered hydrogen bonding and the C–H⋯O hydrogen bonds were also reported.
