Self‐Assembled Diamide Nanotubes in Organic Solvents

Abstract

Wasserstoffbrücken und π‐π‐Wechselwirkungen sind die treibenden Kräfte bei der Selbstorganisation eines Diamid‐Organogelbildners in organischer Lösung zu Nanoröhrchen. Gefrierbruchelektronenmikroskopie (siehe Bild) und Kleinwinkelstreustudien ergaben für die Röhrchen einen Durchmesser von (24.2±0.3) nm, eine Wanddicke von (3.3±0.4) nm und eine Formanisotropie von 1:50 oder mehr.

“…a nanotube), I(q) * (r out ÁJ 1 (qr out ) -r in ÁJ 1 (qr in )) 2 /(q 3 Á(r out 2 -r in 2 ) 2 ) with r out and r in the outer and inner wall radius [37,38]. The first maximum in the interference pattern remains at the same position compared to Eq.…”

Modulation of Viscoelastic Properties of Physical Gels by Nanoparticle Doping: Influence of the Nanoparticle Capping Agent

“…[5] In a few cases charge transfer and ion pairing are also involved. [6] A large variety of sugar and amino acid derivatives are known to rigidify solvents at very low concentrations, sometimes gelling both organic and aqueous media.…”

Hierarchical Supramolecular Self‐Assembly of Nanotubes and Layered Sheets

“…Tubular nano-objects have displayed unique optical, electronic, and magnetic properties and have found potential use in such applications as nanodevices, catalysis, biomimetics, and energy storage. [10][11][12] The supramolecular self-assembly process of mimicking nature to construct biologically active structures can generate ordered complex structures from simple building blocks. In contrast to inorganic [6,7] and macromolecular tubules, [8,9] which have been explored extensively over the last decade, low-molecular-weight organic compounds with their intrinsic merits of diversity, tailorability, and multifunctionality are good candidates for the construction of nanotubes.…”
