Synthesis of hybrid inorganic-organic sol-gel coatings for optics
- Univ. Pierre et Marie Curie, Paris (France). Lab. de Chimie de la Matiere Condensee
The synthesis of transparent hybrid organic-inorganic coatings obtained from condensation between alkoxysilane containing grafted dyes (azo dyes or phthalocyanines) and metal alkoxides precursors has been performed. The Red 17 azo dye, known for its high second order polarizability, was bonded to the silicon oxide network following two procedures: a silylation reaction between Red 17 and triethoxysilane; a coupling reaction between Red 17 and 3-isocyanatopropyltriethoxysilane. Silicon phthalocyanines (known for their third order polarizability and inverse saturable absorption properties) were incorporated into the silicon oxide network by a silylation reaction. Phthalocyanine doped transparent hybrid organic-inorganic coatings were obtained from condensation between diethoxymethylsilane and zirconium propoxide precursors.
