Powders of mesoporous organosilica functionalized with a Non Linear Optical chromophore in the channel pore (azobenzene diethylphosphonate) were achieved in one step and were synthesized by templated-directed co-condensation of tetraethylorthosilicate (TEOS) and the functional organotriethoxysilanes. The materials were characterized by 13C, 31P and 29Si NMR experiments, nitrogen gas adsorption, powder X-ray diffractrion (XRD). Optically transparent and highly ordered multifunctional mesostructured fi lms obtained by evaporation induced self-assembly (EISA approach) approach were deposited on glass or silicon substrates by dipcoating. Thin fi lms were monofunctionalized in the channel pores or bifunctionalized (channel pore/framework) and allowed us to evidence the salt effect induced by an organometallic complex on the structure of the mesostructured fi lm. They were characterized by Grazing Incidence Small Angle X-ray Scattering (GISAXS) and X-ray reflectivity. © 2008 Springer Science+Business Media B.V.
