DEFINITION

Classification: 430/58.3

Containing at least three aryl groups bonded to a single carbon atom in charge transport layer:

(under subclass 58.05) Subject matter wherein the charge transport layer contains a compound having at least three aryl rings bonded to a carbon atom, e.g., R' ₃CR, wherein R' is an aryl group, and R is hydrogen or a carbon containing radical.

(1) Note. Aryl denotes an organic radical derived from an aromatic ring by removal of a hydrogen atom bonded to a ring carbon of the ring system.
