Herein we report a hydrogen-bonded three-dimensional porous supramol. polyknot assembled from a rigid trigonal prismatic triptycene building block with six extended peripheral aryl-carboxyl groups. Within this superstructure, three arrays of undulated 2D rhombic subnets, which display an inclined polycatenation, are interconnected to give an unprecedented uninodal six-connected net with a point symbol of (3.44.610). Such an entanglement results in a trefoil knot motif, which, as the basic repeating unit, is fused and interlocked with itself three-dimensionally to afford a supramol. polyknot. This example highlights the ability of supramol. systems to form topol. complex architectures using geometrically simple building blocks.
