Figure 1: Possible structures of silsesquioxanes or silicone resins. Structure (f) was identified in the present study; (a), (e), and (i) have most probably no choice other than these structures; (b), (d), and (j) are identified with other substituents (see the text below); the presence of (h), (k), and (h) are likely; (c), (g), and (l) is possible structures from the chemical formulae.
