DEFINITION

Classification: 430/58.35

Organic nitrogen in charge transport layer:

Subject matter under subclass QuickMark QuickMark 58.05 wherein the charge transport layer contains an organic nitrogen compound, e.g. amine (RNR' 2[end subscrpt]), cyano (RCN) or nitro (RNO 2[end subscrpt]), etc. wherein R is an organic radical and R' is H or an organic radical.
