Solid-state analyses of supramolecular polyrhomboid and hexagonal networks. (A) Cartoon representation of the formation of rod-like fibers from self-assembly of rhomboid 1. (B) Swelling experiment of hexagon 3 in dichloromethane for the preparation of gels. (C) TEM image of a rod-like fiber made by placing one drop of dichloromethane solution of rhomboid 1 (1.00 mM) onto a carbon-coated copper grid. SEM images of (D) a thin-long fiber drawn from the swelled UPy-functionalized hexagon 2 and (E) a knotted fiber made from solvent-swelled UPy-functionalized hexagon 3.
