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.
