LINKED DIHYDRAZONE-BASED CHARGE TRANSPORT COMPOUNDS, A METHOD FOR PREPARING THE SAME AND A METHOD FOR USING THE SAME

摘要

Provided is an organophotoreceptor with a linked dihydrazone-based charge transport compound which is successfully used in a wet toner to form high quality image keeping the quality of image for a long time. In the organophotoreceptor having a charge transport compound, a charge generation compound and a conductive substrate on the previous two compounds, the charge transport compound is represented by formula 1, in which n is 0 or 1; X is (N,N-disubstituted arylamine) radical; Ar is aryl or heterocyclic radical; A is a first linking group having -(CH2)p- which is possibly branched or linear structure where p is an integer of 3-20 and one or more methylene radicals are selectively substituted to O, S, carbonyl radical, urethane, urea, ester radical, -NR16 radical, CHR17 radical or CR18R19 radical and R16 to R19 are independently H, hydroxyl, thiol, amine, alkyl, heterocyclic, alkaryl, aryl radical or part of ring; and B is a second linking group having -Q-Z-Q`- where Q and Q` are independently O, S or NR1, R1 is H, alkyl, alkaryl or aryl radical and Z is heterocyclic radical.
