Beads on a chain or BOC polymers can be synthesized for silsesquioxane polymers and/or [RSiO1.5]10/12 oligomeric mixtures.1,2 The [RSiO1.5]10/12 oligomer mixtures are made via F- catalyzed rearrangement of -[RSiO1.5]n- compounds and can be di- or polyfunctional as illustrated just below:3   We describe here methods of coupling mixtures of di and polyfunctional T10 and T12 compounds to make beads on a chain polymers. In this presentation we will describe a total of four different synthetic routes to BOC polymers and describe their photophysical characterization.  ReferencesM. Ronchi, S. Sulaiman, N. R. Boston, R.
