Latest Patents

Sehwan Son holds a patent for a "Method for preparation of conjugated arylene and heteroarylene vinylene." This technique describes the preparation of conjugated arylene and heteroarylene vinylene polymers through the thermal conversion of a polymer precursor. The precursor is created by reacting an aromatic ring structure with an aqueous solution of an alkyl xanthic acid potassium salt. The xanthate group serves as a leaving group, allowing for the formation of a prepolymer that is soluble in common organic solvents. The conversion of the prepolymer occurs at temperatures ranging from 150°C to 250°C in the presence of forming gas. Studies indicate that electroluminescent devices made using this method exhibit internal quantum efficiencies that surpass those of prior art, enabling the fabrication of larger area LEDs without pinholes.
