Abstract
An efficient metal-free radical-catalyzed intramolecular silylation method has been developed for the preparation of all-aryl phenazasilines, which can be hardly synthesized by traditional synthetic methods. The easily prepared aromatic and rigid phenazasiline exhibits excellent solubility, high thermal stability, and good optoelectronic properties, which are highly attractive for optical and electronic applications in organic electronics. These advances, in the preparation of all-aryl phenazasilines, offer exciting opportunities for sophisticated molecular design and efficient synthesis of optoelectronic molecules based on the phenazasiline.
