Controlled Hydrogel Fiber Formation: The Unique Case of Hexaphenylbenzene-Poly(ethylene glycol) Amphiphiles

Authors


Abstract

image

Bundles of fibers of hexaphenylbenzene-PEG derivatives in aqueous solutions are inferred from polarized and depolarized light scattering. The water uptake behavior and the self-assembled structures can be controlled by changing the length of the PEG chains. With shorter PEG chains, the objects contain less water and the density of the self-assembled structures is higher.
