Latest Patents
Hongchen Dong holds a patent for a "Soluble branched triaroylbenzene-based polymer and its synthetic method." This invention relates to a novel process of preparing branched polymers through cyclotrimerization. The process utilizes branched organic materials containing triaroylbenzene moieties as the base structural unit. The polymerization method is a simple one-pot reaction that is strictly regioselective and highly functionality-tolerant. It yields oligomeric and polymeric products with a high degree of branching, reaching up to 100% in high yields of up to 99%. The resulting polymers are processible, easily film-forming, and can be transformed into thermosets by heat or irradiation. They can also be crosslinked by UV irradiation to create patterns with nanometer resolution. Furthermore, these polymers can be blended with various macromolecules for general use and can be metallified using organometallic acetylene as building blocks. The ceramization of the patterns obtained from these polymers results in ferromagnetic ceramic patterns with high resolution.
