Abstract
A novel armed-polyrotaxane, comprising two interpenetrating chains of rings with arms, is self-assembled from the flexible ligands 3,3′,4,4′-diphenylsulfonetetracarboxylic acid, as an annular linker motif, and 1,2-di(4-pyridyl)ethylene, as linking rods, which further assembles into a 2D ladder network through hydrogen bonding interactions.
