Superamphiphiles Based on Directional Charge‐Transfer Interactions: From Supramolecular Engineering to Well‐Defined Nanostructures

Abstract

Geben und nehmen: X‐ oder H‐förmige Superamphiphile bilden sich auf Basis gerichteter Ladungstransferkomplexe und führen zur Bildung eindimensionaler Nanostäbe und zweidimensionaler Nanoblätter (siehe Bild, blau: Pyridinium‐Ion, rot: Naphthalinderivate, grün: Naphthalindiimid). Die Überstrukturen bilden sich als Folge ausführlicher Optimierung der Bausteinstrukturen.

Supramolecular Photosensitizers with Enhanced Antibacterial Efficiency

“…Different methods were employed to confirm the formation of the desired supramolecular photosensitizers. [8] As indicated by Figure 2 b, the hydrodynamic diameter of the TPOR selfassemblies is determined to be around 100 nm. The obtained titration isotherm is shown in Figure 2 a.…”

Supramolecular Photosensitizers with Enhanced Antibacterial Efficiency

“…Because of the amphiphilic nature of TPOR and TPOR/(CB [7]) 4 , both of them can self-assemble in water to form well-defined aggregates. [8] As indicated by Figure 2 b, the hydrodynamic diameter of the TPOR selfassemblies is determined to be around 100 nm. However, upon adding CB [7] into the TPOR aqueous solution, the TPOR self-assemblies disappear completely.…”

Hydrogen‐Bonding‐Mediated J‐Aggregation and White‐Light Emission from a Remarkably Simple, Single‐Component, Naphthalenediimide Chromophore

“…[10] NDI derivatives have also been extensively utilized as building blocks for various elegant supramolecular materials, such as synthetic ion channels, [11] organogels, [8,12] hydrogels, [13] nanotubes, [6,14] catenanes, [15] rotaxanes, [16] foldamers, [17] supramolecular photosystems, [18] nanoparticles, [19] and other amphiphilic nanostructures. [20] As a part of our continuing interest in self-assembly of NDI chromophore, we synthesized NDI-1 (Figure 1), which contains a carboxylic acid group that is capable of forming a self-complementary hydrogen-bonding network and a dodecyl chain to provide enhanced solubility in relatively nonpolar solvents. Herein we revealed hydrogen-bonding-mediated, spontaneous J-aggregation [21] of NDI-1 and unprecedented aggregation-induced white-light emission.…”
