Full text not available from this repository.
Organic–inorganic ultraviolet (UV) active hybrid materials have been prepared by a sol-gel process from benzophenone derivatives and tetraethylorthosilicate. The silica particles are spherical in shape and have a narrow size distribution which remains unchanged up to organic chromophore concentrations of 0.2 mmol g)1. At higher concentrations the spheres become less regular and fuse. A ...
