Latest Patents

One of his latest patents is titled "Phosphorescent iridium complex with non-conjugated cyclometalated ligands, synthetic method of preparing the same and phosphorescent organic light emitting diode thereof." This invention discloses a phosphorescent tris-chelated transition metal complex that includes two identical non-conjugated cyclometalated ligands and a ligated chromophore. The metal used in this complex can be iridium, platinum, osmium, or ruthenium. The ligated chromophore is designed to have a lower energy gap compared to the non-conjugated cyclometalated ligand, which effectively inhibits the ligand-to-ligand charge transfer process. This design allows for efficient radiative decay from the excited state of the transition complexes, leading to high-efficiency emissions in blue, green, and even red wavelengths.
