Abstract

original image

Supramolecular fibers possessing an intrinsic large dipole moment can be manipulated with a DC electric field, triggering their alignment in preferred directions on a patterned surface made of Au electrodes supported on an insulating SiOx/Si substrate. The figure shows the electric-field stream lines over the electrodes used to align the nanofibers, calculated using finite element analysis.
