2 1 / 2 3 LAYERS OR THREE-DIMENSIONAL SHAPED BODIES HAVING TWO REGIONS OF DIFFERENT PRIMARY AND/OR SECONDARY STRUCTURE AND METHOD FOR PRODUCTION THEREOF

摘要

The present invention relates to an organically modified polysiloxane, or a layer or a three-dimensional molded article consisting of or containing a derivative of this polysiloxane having a silicon atom totally or partially substituted with another metal atom, wherein the polysiloxane or the organic The component comprises an organic network with thiol-ene-addition products obtainable through a two- or multiphoton polymerization reaction, bonded to silicon and/or other metal atoms via carbon and/or oxygen, In case the molded body is obtained by the following method and has two regions with different primary- and/or secondary structures: a) providing a substrate or mold, b) a metal and/or a half Providing a material selected from among metal-containing sols, gels and organically modified polysiloxane-containing materials, wherein the material provided has a free SH-group and an isolated C=C-2 bond, c) the provided above Applying a material onto a substrate, attaching it to a substrate, or inserting the material into a mold, d) selectively using a two- or multiphoton-polymerization of a selected area of the material on the substrate or in the mold. Exposing, e) can be obtained by thermally and/or photochemically treating the entire material on the substrate or in the mold, provided that steps d) and e) can be carried out in any order. have. The material provided according to step b) is preferably 1. (a) a material having an organic group bonded to the metal/semimetal through an oxygen bridge or through a carbon atom, substituted with one or more SH-groups, and (b ) A mixture consisting of or containing purely organic compounds having two or more isolated C=C-bonds or containing such substances and compounds, 2.(a) having one or more isolated C=C-2 bonds , A substance having an organic group bonded to a metal/semimetal through an oxygen bridge or through a carbon atom, and (b) a purely organic compound substituted with two or more SH-groups, or containing such substances and compounds. Mixture, and 3. (a) a substance having an organic group bonded to the metal/semimetal through an oxygen bridge or through a carbon atom, substituted with one or more SH-groups, and (b) at least one isolated C= It is selected from mixtures containing materials consisting of or containing organic groups bonded to metal/semimetals with C-bonds, through oxygen bridges or through carbon atoms.
