Abstract:
1. A charge transporting material, comprising: a compound represented by Formula (Cz-1), wherein a content of an impurity represented by Formula (I-1) in the charge transporting material is from 0.000% to 0.10% when the content is calculated as a proportion of an absorption intensity area of the impurity represented by Formula (I-1) with respect to a total absorption intensity area of the charge transporting material, as measured by high-performance liquid chromatography at a measurement wavelength of 254 nm: wherein in Formula (Cz-1), each of R R each of n1 to n4 independently represents an integer from 0 to 4; and n5 represents an integer from 0 to 5: wherein in Formula (I-1), R n1 to n4 are the same integers as defined for n1 to n4 in Formula (Cz-1) respectively.
