Synthesis and properties of chromophore-functionalized monovinylsilsesquioxane derivatives

A facile and efficient Pd-based Suzuki-Miyaura coupling reaction leading to mixed chromophores with styryl fragments, enabling their further application, is presented. We also disclose their use in the formation of monofunctionalized silsesquioxanes with a chromophore group covalently bound to a T 8...

Description
Summary:A facile and efficient Pd-based Suzuki-Miyaura coupling reaction leading to mixed chromophores with styryl fragments, enabling their further application, is presented. We also disclose their use in the formation of monofunctionalized silsesquioxanes with a chromophore group covalently bound to a T 8 core that have been prepared via a cross-metathesis reaction. These new materials were studied in terms of their photophysical and also thermal properties. Herein, an effective and selective synthesis of chromophore-functionalized monovinylsilsesquioxane derivatives by a cross-metathesis reaction along with discussion of their photophysical and thermal resistance properties is disclosed.
