“…Similar results were achieved with anthrachinone and perylene dyes (s. Figure , parts b and c). The photostability of the azo dye proved to be higher in the hybrid matrix than in pure inorganic or organic matrixes . Hybrid pigments might find applications in fields where conventional organic pigments fail due to their higher solubility or lower thermal stability.…”

“…The chromophores after silylation are accessible to common hydrolysis and polycondensation reactions together with the more simple precursors shown in Figure , thereby giving rise to an even broader range of class II materials. The covalent attachment together with the higher network density in hybrid polymeric materials enables one to enlarge the incorporated amount of the organic ingredients, reduces dye leaching problems, and, in special cases, leads to stabilizing effects, possibly by isolating the dye molecules from each other or from their degradation products as well as reducing the oxygen permeation rates inside the matrix. ,,− …”

Structural features and properties are further extended by the additional use of transition metal alkoxides 30 and organic monomers or prepolymers.…”

The homogeneous combination of inorganic and organic moieties in a single-phase material provides unique possibilities to tailor the mechanical, electrical, and optical properties with respect to numerous applications. The synthetic pathway follows the well-known sol−gel procedure. Nevertheless, the establishment of defined hybrid products necessitates a basic understanding of the underlying chemistry as well as of the parameters influencing the processing techniques. Modern spectroscopy provides versatile tools, e.g., multinuclear NMR experiments and Raman scattering to investigate the sol−gel processing of organo(alkoxy)silanes in their co-condensation reactions with main group or transition metal alkoxides as well as in their copolymerization reactions with each other or with organic molecules. This almost infinite modular design concept has led to the industrial application of coatings for transparent plastics, glasses, and metals to prevent these substrates from mechanical abrasion, permeation, or corrosion or to achieve decorative functions. Further passive optical properties can be realized by generating submicrometer surface patterns. By the integration of organic or inorganic dopants, like dyes or nanoparticles, highly sophisticated multifunctional hybrid polymers or nanocomposites are accessible and have become important to achieve active optical functions, e.g. switching, light harvesting, or storage media. Recently developed porous and dense bulk hybrid polymers have shown that the range of possible applications is not limited to surface refinement by coatings. This contribution reviews the present status as well as the perspectives of these types of advanced materials.

“…[64] The covalent attachment of dyes in the ORMOCER matrix via silanized dyestuffs increases the leaching and photochemical stability of the dyes. [65,66] Patterned surfaces for optical applications are another important application of ORMOCER coatings. Embossing techniques in combination with UV-curable ORMOCER layers lead to sub-mm-structures on transparent substrates like glasses and polymers.…”

Hybrid materials have found widespread applications in recent years and are one example for the bottom‐up approach to nanotechnology: materials and phases are generated by physical or chemical means from precursor compounds forming nanoscale or nanocomposite materials. This review describes basic principles and several applications of inorganic–organic polymers using organically crosslinked heteropolysiloxanes (ORMOCERs) based on the sequential synthesis of inorganic and organic networks.
