Molecular-level and particle-dispersed inorganic-organic hybrids, containing TiO as the inorganic component, have been prepared in order to study the effect of the introduced inorganic phase dimension on the structure and properties of the hybrids. The hybrids prepared from silanol-terminated polydimethylsiloxane (PDMS) and titanium ethoxide (Ti(OEt)) in the molar ratios of Ti(OEt)/PDMS=1, 2 and 4 were transparent with no visible particles, thus considered as molecular-level hybrids.

The coloration behavior of the inorganic/organic hybrids prepared from polydimethylsiloxane (PDMS) and chemically modified metal alkoxides was investigated by ultraviolet-visible (UV-VIS), X-ray photoelectron (XPS) and electron spin resonance (ESR) spectroscopies. Although the hybrids were transparent in the visible region, a broad absorption was observed from the visible to UV regions, leading to a color from yellow to wine-red. The color and the absorption edge of the hybrids depend on the inorganic components derived from metal alkoxides.
