Summary: Charge transfer complexes (CTC) can be readily introduced into materials by cohydrolysis-copolymerisation of bis-silylated oligothiophenes (bi-, ter- and tetra-) as precursors with TMOS and TEOS in the presence of TCNQ. The surfaces specific BET showed that in case of xerogels prepared by variation (4, 6, 8 and 12) unit equivalents of TEOS are higher than the xerogels prepared by TMOS. The small angle of x-ray scattering (SAXS) studies show an organisation only for the gel 2,5’’-bis(trimethoxysilyl)terthiophene/TCNQ/TMOS (1:1:4) which is essentially absent after elimination of TCNQ. The pick 4.6 Å showed that there is an organization structure as lamellar structure, which formed between these precursors. Transmission microscope studies show there are spheres by diameter 5µm and electron microscope studies (EDAX) show the presence of spheres rich in silicon in the case of the gels prepared in the presence of TCNQ. These phenomena showed that the TCNQ contributed more than 25% into formation of these spheres in this materials.
