π‐Conjugated Oligo‐(p‐phenylenevinylene) Rosettes and Their Tubular Self‐Assembly

Abstract

Hierarchical self‐assembly: Oligo(p‐phenylenevinylene)s with pendant diamino triazine moieties can self‐assemble through hydrogen‐bonding interactions to give hexameric rosettes (see picture, left). These rosettes further organize into large supramolecular tubules (right) with perfect space filling.

The Versatile Thiophene: An Overview of Recent Research on Thiophene‐Based Materials

“…[45] H-bonding-directed self-assembly has been widely explored in conjugated materials. [46] Hydrogen-bond-driven self-assembly modalities of thiophene oligomers were demonstrated by P. Baüerle and co-workers with the biohybrid oligothiophene B (Fig. 1).…”

Hydrogen bond directed assembly of oligothiophene/fullerene superstructures on Au(111)

“…To a first-order approximation the assemblies are mirror images. Chiral rosette formation as a consequence of H-bonding and surface adsorption has been studied before with both chiral [30,32,39,40] and achiral [33,34] monomers.…”

“…Self-complementary H-bonding has been shown to compete with strong adsorbate-substrate and substratesubstrate interactions to program the formation of closed cyclic assemblies, or rosettes [27,[29][30][31][32][33][34][35][36][37][38][39][40], that can be visualized with atomic resolution on surfaces [41][42][43]. Among the motifs, phthalhydrazide (PH) derivatives have been found to form H-bonded cyclic trimers (e.g., (PH) 3 , Fig.…”

Metallacycles or coexistence of isomeric metallacycle and chain: Anion-dependent luminescent Ag complexes of a flexible diaminotriazine–imidazole ligand

“…Melamine derivatives are well known for their brilliant supramolecular interaction abilities to construct remarkable http architectures which may have applications in host-guest chemistry, catalysis, anion recognition, sensoring, electronics and magnetism [16][17][18][19][20][21][22][23]. Furthermore, the excellent H-bonding ability of diaminotriazinyl (DAT) group has been successfully used in combination with coordination bonds in some DAT based rigid ligands for crystal engineering [24][25][26][27][28].…”
