Nanocomposites (G' (1) ), (G' (2) ) and (G' (3) ) exhibited mainly morphological differences while in some cases composition differences when using TEOS as gelator., Some simple metal-containing compounds as (O3SCF3)Ag(PPh3)(HOC5H4N), CuCl2 center dot NC5H4OH and CuCl2 center dot NCCH2C6H4OH-which are useful models of the most complexes (G (5) ), (G (6) ) and (G (7) ) were also prepared and incorporated in amorphous silica.
