Large‐scale 3D assembly of 1D ZnSe nanorods into microstrings (see figure) by simple application of a dc electric field is reported. The ordered rods exhibit polarization perpendicular to their long axis in fluorescence emission, contrary to the randomly ordered rods. The switchable assembly into long‐range microstructures with unique polarization behavior holds great promise for novel applications.
