Evaluation of dipole moment of polyhedral oligomeric silsesquioxane compounds† The aggregation state of polyhedral oligomeric silsesquioxane (POSS) within a polymer matrix plays a crucial role. Molecular interactions are key driving forces for aggregation, and one of the key physical parameters is the dipole moment (DPM). Quantum calculations such as density functional theory (DFT) calculations can be used to estimate the DPM.

Synthesis of a series of octaalkoxy-substituted cage silsesquioxanes catalyzed by zinc acetate† Octaalkoxy-substituted polyhedral oligomeric silsesquioxane (8RO-POSS) is an attractive starting material for producing silicone resins. However, polymers derived from 8RO-POSS via the sol–gel process have seldom been reported owing to their synthetic difficulty.
