Mesoporous Hybrid Thin Films (MHTF) of a variety of compositions and embeddedorganic functions are produced by combining sol-gel synthesis, template self-assembly andsurface modification. One-pot or post-grafting strategies permit to modify the pore surfacebehavior. Highly controlled MHTF issued from a reproducible and modular synthesis can beused as building blocks for more complex structures, presenting order at larger scales, and novelproperties derived from this multiscale order. Multilayer stacks of MHTF presenting specific anddifferent functions and frameworks located in a well-defined position have been produced bycombining sequential film deposition, selective functionalization and dissolution. These systemspresent new properties such as localized chemistry or modulable photonic crystal behavior.
