Synthesis and properties of chromophore-functionalized monovinylsilsesquioxane derivatives

Abstract

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 T₈ core that have been prepared via a cross-metathesis reaction. These new materials were studied in terms of their photophysical and also thermal properties.
