)hexyl)thiophene and subsequent cleavage of a tetrahydropyranyl group. Acid-catalyzed polycondensations of tetraethoxysilane (TEOS) were carried out in the presence of these polymers to give homogeneous composites with silica. The resulting composite materials were characterized by UV−vis and emission spectra.
