    • The invention relates to a layer or a three-dimensional shaped body composed of or comprising an organically modified polysiloxane or a derivative thereof wherein some or all of the silicon atoms have been replaced by other metal atoms, where the organic component of the polysiloxane or derivative thereof has an organic network comprising thiol-ene addition products bonded via carbon and/or oxygen to silicon and/or other metal atoms, which are obtainable via a 2- or multiphoton polymerization reaction, where the body has two regions having different primary and/or secondary structures, obtainable by the following method: a) providing a substrate or a mould, b) providing a material selected from metal- and/or semimetal-containing sols, gels and organically modified, polysiloxane-containing materials, where the material provided has free SH groups and isolated C=C double bonds, c) applying or attaching the material provided to the substrate or introducing it into the mould, d) selectively exposing a selected region of material present on the substrate or in the mould with the aid of two- or multiphoton polymerization, e) thermally and/or photochemically treating all the material present on the substrate or in the mould, with the proviso that steps d) and e) can be conducted in any sequence. The material provided in step (b) is preferably selected from 1. a mixture composed of or comprising (a) a material having organic groups which are bonded to the metal/semimetal via an oxygen bridge or via a carbon atom and which are substituted by one or more SH groups, and (b) a purely organic compound having two or more isolated C=C bonds, 2. a mixture composed of or comprising (a) a material having organic groups which are bonded to the metal/semimetal via an oxygen bridge or via a carbon atom and which have one or more isolated C=C double bonds, and (b) a purely organic compound substituted by two or more SH groups, und 3. a mixture composed of or comprising (a) a material having organic groups which are bonded to the metal/semimetal via an oxygen bridge or via a carbon atom and which are substituted by one or more SH groups, and (b) a material having organic groups which are bonded to the metal/semimetal via an oxygen bridge or via a carbon atom and which have one or more isolated C=C bonds.
