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.

Four different synthetic methods for preparation of aromatic sialnes have been developed and the hydrosilylation route has been proved to be one as the most commercially significant. A series of specialty aryl silanes have been synthesized for the potential applications of high performance and high temperature as silane coupling agents. The thermal stabilities of the bridged aromatic silanes have been examined using thermal gravimetric analysis (TGA) and compared against the gamma-substituted alkylsilanes and phenyltrimethoxysilane. These materials have greater thermal stability than the gamma-substituted, but marginally lower than phenyltrimethoxysilane.

We systematically study the electronic structure, carrier mobility and work function of imine based 2D-COFs. The bandgaps of these semiconducting materials can be tailored by doping with nitrogen for tunable electronic/optoelectronic properties.
