Organic modified siloxanes of the type RSi(OMe 2 ) 2 (CH 2 ) 3 C 6 D 4 (CH 2 ) 3 (OMe 2 ) 2 SiR [R = Me ( 4 ), R = OMe ( 5 )] were sol‐gel processed employing solvents of different polarity (MeOH and THF) to yield the corresponding inorganic‐organic hybrid polymers X4a — X5b with different physical properties. These polymers were investigated by multinuclear ( 2 H, 13 C, and 29 Si) solid state and 1 H suspension state NMR spectroscopy, including dynamic NMR techniques, in order to correlate the mobilities of these xerogels with physical properties, especially with the cross‐linkage.
