摘要:
An enamine derivative of formula (I) wherein the groups R' are the same or different and each is a fluorine-containing substituent of the formula RfO- or (Rf) 2 N- in which Rf is fluoroalkyl, fluoroaryl or fluoroaralkyl ;
R 2 and R 3 are the same or different and each is alkyl, aryl, aralkyl, an alicyclic group or a heterocyclic group, or NR 2 R 3 is a 5- or 6-membered cyclic group, the groups R 2 and R 3 or NR 2 R 3 each independently optionally being unsubstituted or bearing one or more substituents ; Ar 1 and Ar 2 are the same or different and each is aryl or arylene, Ar 1 and Ar 2 each independently optionally being unsubstituted except for the group or groups R 1 or bearing one of more substituents in addition to the group or groups R 1 ; k is zero or 1; and m and n are the same or different and each is zero or an integer of 1 to 3, provided that m and n are not both zero is effective as a charge transport material in an electrophotographic member excellent in sensitivity, residual potential, durability and the like electrophotographic properties. Intermediates and production process are described.
