Long-range ordered columns of a hexabenzo[bc,ef,hi,kl,no,qr]coronene–polysiloxane complex: towards molecular nanowires

About Supramolecular Assemblies of π-Conjugated Systems

“…The extended columns could be visualized by TEM due to their electron conductivity ( Figure 48). 319 Since polyelectrolytes can be deposited in a controlled way, this approach of ionic selfassembly can tremendously aid the orientation and positioning on a surface. 320 Another approach is using organogelators as a director to control the morphology of the liquidcrystalline film.…”

Ionic Self‐Assembly: Facile Synthesis of Supramolecular Materials

“…Thünemann and Müllen published the first work on the ISA of large, charged, and conjugated discotic moieties aligned by polyelectrolyte with either an hydrophobically modified polyethyleneimine [67] or an amino-functionalized polysiloxane. [68] As compared to the bare discotic system which is already liquid-crystalline and a promising organic conductor, the polyelectrolyte-supported systems show higher intra-columnar order and the formation of very large extended columns. Figure 5 shows an electron image of a thin layer of such a sample where the stacked columns can be directly visualized due to their electron conductivity.…”

Oligotriphenylene Nanofiber Sensors for Detection of Nitro‐Based Explosives

“…One‐dimensional (1D) π ‐conjugated nanosystems have received much attention as advanced electronic and photonic materials and devices 1–4. Conjugated polycyclic aromatic hydrocarbons (PAHs) are well‐known for exhibiting the ability to self‐assembly into 1D nanostructures through strong π − π stacking interactions 5–10. Triphenylene represents the smallest example of an all‐benzenoid PAH,11–13 and its derivatives exhibit unique electro/photoluminescence,14, 15 charge‐carrier mobility,16–18 energy migration,19, 20 and thermal and chemical stability 21, 22.…”
