The present invention provides an organophotoreceptor comprising an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising:(a) a charge transport material having the formulaX―Z―X'???where X and X' are, each independently, a (9-fluorenylidene)malononitrile group, and Z is a linking group having the formula -(CH2)m-, branched or linear, where m is an integer between 1 and 30, inclusive, and one or more of the methylene groups may be replaced by O, S, C=O, Si=O, S(=O)2, P(=O)2, an aromatic group, a heterocyclic group, an aliphatic cyclic group, a Si(R1)(R2) group, a BR3 group, a NR4 group, a CHR5 group, or a CR6R7 group where R1, R2, R3, R4, R5, R6, and R7 are, each independently, H, halogen, hydroxyl, thiol, an alkoxy group, an alkyl group, an alkenyl group, an aromatic group, a heterocyclic group, or a part of a cyclic ring; and(b) a charge generating compound.Corresponding electrophotographic apparatuses and imaging methods are described.

A simple procedure is described which allows one to prepare polymercaptobenzenes starting from chlorobenzenes.The reactions of all the possible chlorobenzenes with Me2CHSNa in HMPA give the corresponding (isopropylthio)benzenes which can be cleaved by adding sodium to the reaction mixtures to give the arenethiolates in good yields.In some cases the polymercaptobenzenes were isolated after treatment with acid; in other cases methyl iodide was added to the reaction mixture and poly(methylthio)benzenes were obtained.It is suggested that the (isopropylthio)benzenes react with sodium to give the corresponding radical anions which fragment at the sulfur-alkyl bond to give the arenethiolates.
