Hierarchical Self-Organization of AB _n Dendron-like Molecules into a Supramolecular Lattice Sequence.

ABSTRACT: To understand the hierarchical self-organization behaviors of soft materials as well as their dependence on molecular geometry, a series of AB _n dendron-like molecules based on polyhedral oligomeric silsesquioxane (POSS) nanoparticles were designed and synthesized. The apex of these molecules is a hydrophilic POSS cage with 14 hydroxyl groups (denoted DPOSS). At its periphery, there are different numbers (n = 1-8) of hydrophobic POSS cages with seven isobutyl groups (denoted BPOSS), connected to the apical DPOSS via flexible dendron type linker(s). By varying the BPOSS number from one to seven, a supramolecular lattice formation sequence ranging from lamella (DPOSS-BPOSS), double gyroid (space group of Ia3̅d, DPOSS-BPOSS₂), hexagonal cylind
