Latest Patents

One of his latest patents is a method for preparing polycarbosilane by catalytic rearranging. This invention provides a method for preparing polycarbosilane through the decomposition and rearrangement of a cyclic silane compound or chain polysilane under the catalysis of a boron-containing catalyst in a trace amount. The method utilizes poly(dimethylsilane) or its thermal decomposition product as the raw material, with less than 1 wt % of the boron-containing catalyst added. The process involves gradually increasing the temperature to perform the thermal decomposition/rearrangement reaction, resulting in solid polycarbosilane with a higher ceramic yield. This method is advantageous due to its short reaction time, high synthetic yield, good product quality, simple equipment, and safe operation. The polycarbosilane produced serves as a polymeric precursor for SiC, which can be used in the preparation of SiC fibers and SiC-based composite materials.

Another notable patent involves a polycyclic fused ring type π-conjugated organic material, along with the processes for producing both the material and its intermediate. This invention describes a method where a starting material is dimetalated with an organometallic base and subsequently trapped with an organosilicon reagent. The resulting intermediate undergoes an intramolecular reductive cyclization reaction, leading to the production of a polycyclic fused ring type π-conjugated organic material. This material exhibits excellent light-emitting and charge-transporting properties, making it valuable for various applications.
