Rh()-catalyzed synthesis of amino-side-chained poly(phenylene vinylene) C-H bond olefination

A Rh( iii )-catalyzed hydrazine-directed C-H olefination approach was developed for synthesizing amino-side-chained poly(phenylene vinylene) (PPV). The creation of such a divergent portfolio of PPV candidates enabled the discovery of a mega Stokes shift, high fluorescence quantum yield, and solid-state fluorescence, highlighting the great prospects of our synthetic protocol as an innovative tool. A divergent portfolio of PPV candidates has been prepared through a C-H olefination method, which led to the discovery of a giant Stokes shift, high fluorescence quantum yield and solid-state fluorescence.
