An easy and simple synthetic route is reported to obtain highly crystalline
lamellar silicon fluorides by using amorphous silica gel and neutral N-dia
lkylamines, H2N(CH2)(n)NH2 (n = 8, 10 and 12) as precursors. The inorganic-
organic hybrids formed present a degree of crystallinity much higher than t
hat observed for lamellar silica synthesized through the sol-gel process. T
his new procedure can open an important route of synthesis applied to mater
ials science; (C) 2000 Elsevier Science S.A. All rights reserved.
