The synthesis and self-assembly of disc-cube dyads with spacers of different lengths†
Abstract
Disc-cube dyads with a polyhedral oligomeric silsesquioxane (POSS) molecule covalently attached to a hexa-peri-hexabenzocoronene (HBC) molecule were designed and synthesized. The results demonstrate that the length of a spacer plays an important role in the self-assembly behavior of the HBC–POSS dyad.
