Paper Abstract

It is well known that topological defects of a liquid crystal can trap colloidal particles and polymers. However, it remains unclear whether low-molecular-weight (LMW) non-LC molecules can aggregate at topological defects, because entropy towards uniform distributions becomes more dominant for smaller molecules. We show by a simple theoretical argument that topological defects indeed give rise to non-uniform distributions of such LMW guest molecules. The relaxation of the high free energy density of topological defects by the presence of LMW guest molecules is strong enough to overcome the contribution of entropy. We briefly discuss the relevance of our theoretical arguments to experiments.
