AbstractNew fluorinated inorganic-organic hybrid polymers (ORMOCER*s) for integrated optics were synthesized via hydrolysis and condensation (sol-gel processing) of functionalized pentafluorophenylalkoxysi lanes followed by organic crosslinking reactions. Process parameters (catalyst, temperature and ratio of educts) were optimized to achieve low transmission losses at the most important wavelengths for telecommunication in the NIR range: 1310 nm and 1550 nm.The result is a photopatternable transparent ORMOCER (negative resist behavior) with excellent low losses: 0.20 dB/cm at 1310 nm and 0.30 dB/cm at 1550 nm.Besides their high transparency the fluorinated ORMOCERs show a variety of other properties enabling their use as waveguide materials within the production of optoelectronic devices and related thin film technology: good wetting and adhesion on various substrates (e.g. glass, silicon and several polymers), low processing temperatures (postbake below 160 °C), high thermal stability (decomposition > 250°C) and a tunable refractive index.

ABSTRACTInorganic-organic hybrid polymers were prepared by radical polymerization of methacrylic acid or methyl methacrylate with the (meth) acrylate-substituted oxozirconium and oxotitanium clusters Zr6(OH)4O4(OMc)12(OMc = methacrylate), Zr4O2(OMc)12, Ti6O4(OEt)8(OMc)8 and Ti4O2(OPri)6(OAcr)6(OAcr = acrylate). A few mol% of cluster is sufficient for an efficient cross-linking of the polymer chains. Small-angle X-ray scattering data indicate that the cluster size is retained in the polymers and that the microstructure of the cluster cross-linked samples can be described by a dispersion of identical spherical or disk-shaped clusters in the polymer. The obtained hybrid polymers exhibit a higher thermal stability because depolymerization reactions are inhibited. Contrary to undoped poly (methyl methacrylate), the cluster cross-linked polymers are insoluble but swell in organic solvents. The solvent uptake upon swelling decreases with an increasing amount of polymerized cluster.
