    • X-ray quality crystals of dimers 8, 12, and 15 were grown by sublimation of the pure solids in a vacuum. The structure and atomic numbering scheme for 8 is displayed in Figure 8, and the bond lengths (Å) and bond angles (deg) for this structure are given in the Supporting Information.

    • It is likely, based on careful viscosity studies, that the polymers are highly branched structures with a significant contribution of cyclic structures.
    • Cis syndiotactic ladder structures have been proposed to account for the solublity of polysilsesquioxanes which, based on the number of siloxane bonds to each silicon, should be cross-linked and insoluble. See: Brown, J. F. Jr. J. Polym. Sci. Part C 1963, 83. It is likely, based on careful viscosity studies, that the polymers are highly branched structures with a significant contribution of cyclic structures. See: Frye, C. L.; Collins, W. T. J. Am. Chem.
