Hierarchical organic-inorganic materials are increasingly taking their position in the free spaces left between inorganic chemistry, polymer chemistry, organic chemistry, and biology. The controlled design of hybrid organic-inorganic interfaces allows the construction of materials presenting complex hierarchical structures; a particularly interesting challenge for the materials chemists. In particular, the integration between the ''chimie douce� driven sol�gel processing'' and ''soft matter'' is a strong success as both can interact without disrupting their own function. These new approaches where chemistry is strongly coupled with processing have been coined �Integrative Chemistry�. They provide the ability to scissor condensed matter at several length scales where final materials and systems will be macroscopically shaped one-dimensional (1D), two-dimensional (2D) or three-dimensional (3D). We will present the main approaches we are developing for multiscale texturation of inorganic and hybrid materials: Nanocasting, cooperative self-assembly (molecular and polymeric surfactants), multiple templating with bigger static (latex, etc) or dynamic templates (breath figures), organogelators templating, .... Moreover the use of all this various templating strategies combined with chimie douce and smart processing methods such as multilayers deposition, aerosols, ink jet printing, electrospinning, foaming, led in the past years to an amazing mushrooming of new hierarchical functional materials with many interesting properties. Some of these materials will be presented.
