We report the synthesis of oriented silica mesostructure films by surfactan
ts such as hexadecyl-trimethylammonium bromide (C(16)TMA) or 11-ferrocenylu
ndecyl-ammonium bromide (Fe-TMA) surfactant on a sol-gel method by spin coa
ting. Xray diffraction of the film showed that the film oriented in a lamel
lar, hexagonal or cubic structure, just depending on C(16)TMA's concentrati
on. In the case of lamellar oriented film by Fe-TMA, linear temperature dep
endent conductivity properties were observed. (C) 1999 Elsevier Science Lim
