摘要：
Gold nanoparticles possessing a positionally ordered 3D liquid crystalline phase in the bulk have been prepared (see figure). Induction of the mesophase results from the synergy between the gold core and the non-mesogenic dendrons. These particles are also ferromagnetic up to 400 K and are able to self-organize in a 2D hexagonal array on solid substrates, opening perspectives in the field of information storage at the molecular level.
