Fig. 12 Neat melamine Hekates 40, their 1 1 host-guest complexes 41,42 and the 1 3 aggregates of a melamine core with three arms 43 and 44. The disk-shaped aggregates 41 stack in a Colrd phase [99]. The Janus-type Hekate 42 arrange in a Colh phase with hexagonal superstructure of the nanosegregated semi-perfluorinated chains [105]. The supramolecular Hekate discs 43-45 self-assemble by hydrogen bonding of the three arms around a melamine core...

Self-assembly by hydrogen bonding interactions is a very usual feature (together with the electron donor/acceptor interactions) in natural and unnatural non-covalent assembly of molecules18. 

Per-amino-CyDs form various self-assemblies by hydrogen bonding in water [159-161]. Cationic amphiphilic j8-CyDs 41, 42, substituted with hydrophobic n-alkylthio chains at the primary hydroxyl side and hydrophilic co-amino-oligo-(ethylene glycol) units at the secondary side, formed bilayer vesicles with a diameter of 30-35 nm (when alkyl = hexadecyl) or nanoparticles with a diameter of ca. 120 nm (when alkyl = hexyl) in water [159]. Sulfated amphiphilic CyDs 43-45...

Drain et al. reported linear porphyrin arrays self-assembled by hydrogen bonding or metal-ion coordination into lipid bilayer membranes [99]. In Fig. 25, linear porphyrin tapes by hydrogen bonding between 5,15-bisdiacetamidopyridyl porphyrins 39 and 5,15-diuracil porphyrins 40 are shown. The size of the porphyrin assembly can self-adjust to the thickness of the bilayer and 85 nA of photocurrent was observed.
