Polyphenylsilsesquioxane Partially-substituted with Germanium: Refractive Index Controllability and Thermal Stability

Polyphenylsilsesquioxane Partially-substituted with Germanium: Refractive Index Controllability and Thermal Stability

The refractive index of a novel silicon-germanium ladder copolymer synthesized by partially substituting silicon in the main chain of polyphenylsilsesquioxane by germanium could be controlled between 1.558 and 1.573 by changing the content of germanium up to 10 mol%, without losing thermal stability...

Zusammenfassung:The refractive index of a novel silicon-germanium ladder copolymer synthesized by partially substituting silicon in the main chain of polyphenylsilsesquioxane by germanium could be controlled between 1.558 and 1.573 by changing the content of germanium up to 10 mol%, without losing thermal stability over 500 °C.
