Nanofibers from self-assembly of an aromatic facial amphiphile with oligo(ethylene oxide) dendrons.
Novel block facial amphiphiles consisting of a laterally extended aromatic segment and oligo(ethylene oxide) dendrons as a flexible segment were synthesized in a stepwise fashion and their aggregation behavior was investigated in aqueous solution; self-assembly into elongated nanofibers with a uniform diameter of 7 +/- 0.5 nm and lengths up to several hundred nanometers was observed.
