    摘要: 4-aminobiphenyl derivative arylamine compounds are formed by providing an iodinated organic compound; substituting the iodinated organic compound at carboxylic acid groups thereof to provide ester protecting groups; conducting an Ullman condensation reaction to convert the product of step (ii) into an arylamine compound; and conducting a Suzuki coupling reaction to add an additional phenyl group to the arylamine compound in the 4-position relative to the nitrogen.

    摘要: An organic electroluminescent device comprising an anode, an electroluminescent region, and a cathode. The luminescent region comprises a light-emitting material of Formula I wherein R1 is independently selected from the group consisting of a hydrogen, an alkyl group, an aryl group, a heteroaryl group, an alkoxy group, an amino group, an alkyl amino group, and an aryl amino group; R2 is independently selected from the group consisting of hydrogen, a hetero atom, and an alkyl group; R3 is independently selected from the group consisting of hydrogen, an alkyl group, an aryl group, a heteroaryl group, an alkoxy group, a halogen atom, and a cyano group; and, R4 is independently selected from the group consisting of hydrogen, an alkyl group, an aryl group, a heteroaryl group, an alkoxy group, a halogen atom, and a cyano group.
