Charge transporting material and organic electroluminescence device

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 R1 to R4 independently represents a fluorine atom, an alkyl group, an aryl group, a silyl group or a cyano group, provided that when R1 to R4 respectively exist in plurality, a plurality of R1's to a plurality of R4's may be the same or different respectively;
• R5 represents an alkyl group, an aryl group or a silyl group, provided that R5 does not represent a carbazolyl group or a perfluoroalkyl group, and when R5 exists in plurality, a plurality of R5's may be the same or different or a plurality of R5's may be bonded together to form an aryl ring;
• 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), R1 to R4 are the same atoms or groups as defined for R1 to R4 in Formula (Cz-1) respectively;
• and
• n1 to n4 are the same integers as defined for n1 to n4 in Formula (Cz-1) respectively.
