The peripheral architecture of Aryl Polyhedral Oligomeric Silsesquioxanes (POSS) plays a significant role in observed macroscopic properties including phase transistions, thermal stability, and solubility. A relationship between these properties and POSS packing efficiency is offered, providing evidence that peripheral interactions require consideration in resolving the observed phenomena. These interactions further assume a pivotal role in determining POSS phase behavior in host materials such as low molecular weight solvents and polymers. The findings reported herein will improve the efficacy of designing POSS molecules for the purpose of fabricating multifunctional polymer matrix composites and protective barrier coatings for organic materials.
