CHARGE TRANSPORTING MATERIAL AND ORGANIC ELECTROLUMINESCENCE DEVICE |
摘要 |
In order to provide an organic electroluminescence device with high luminous efficiency and good durability, the present invention provides a charge transporting material including a compound represented by Formula (Cz-1) wherein the content of a particular halogen-containing impurity in the charge transporting material is from 0.000% to 0.10% when the content is calculated as a proportion of the absorption intensity area of the impurity with respect to the total absorption intensity area of the charge transporting material, as measured by high-performance liquid chromatography at a measurement wavelength of 254 nm, and an organic electroluminescence device wherein the charge transporting material is included in an organic layer: wherein in Formula (Cz-1), each of R1 to R5 independently represents a particular atom or group; and each of n1 to n5 independently represents a particular integer.
