Abstract Organosilicon compounds whose structure is based on the stable Si–O
bonds show high chemical and thermal stability. Incorporation of organic groups into
their molecules results in the materials which combine the properties of the Si–O
skeleton and those of organic moieties. Hydrosilylation, i.e., catalytic addition of
Si–H groups to carbon–carbon double bonds, is a convenient route to prepare
organofunctional silicon compounds. In this chapter, the work that has been done
since the year 2000 on functionalization via hydrosilylation of polysiloxanes, cubic
oligomeric silsesquioxanes, and spherosilicates, i.e., the main classes of organosilicon
compounds containing Si–O bonds, is reviewed. The emphasis is put on spectroscopic
investigations of the functionalization process or its products.
12.1 Introduction
Organosilicon oligomers and polymers whose structure is based on Si–O bonds are
a unique class of chemical compounds. They show a number of advantageous
properties, such as high chemical and thermal stability or bioinertness. An attractive
feature is that such compounds of various molecular architectures can be prepared.
Oligo-/polysiloxanes and oligo-/polysilsesquioxanes are the main classes of
organosilicon compounds containing Si–O bonds. The molecules of the former can
be linear or cyclic, and their backbone is composed of repeating Si–O linkages
(general formula: [–R 1 R 2 SiO–] n ) [1], whereas in the latter each Si atom is surA. Chechelska-Noworyta Á J. Mrówka Á M. Owińska Á M. Hasik (&)
