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

Abstract

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.
