Abstract Monolithic crack-free condensates have been synthesized by hydrolysis and polycondensation of tetraethoxytitanium(IV) and γ-glycidoxypropyltrimethoxysilane. The local order in these materials has been studied by large angle X-ray scattering (LAXS) as well as the influence of Ti4+-Ti3+ transition induced by UV irradiation. The polysiloxane is characterized by a quasiregular arrangement of the side-chains similar to the proposed models for liquid-crystalline polysiloxane. Titanium atoms, in an octahedral environment, are coordinated to the diol functions. If the metal percentage is higher than 20%, the titanium atoms are distributed on several sites.
