This invention relates to a novel organophotoreceptor comprising:
(a) at least one charge transport material comprising a fluorenone hydrazone having a combination of groups thereon, the combination of groups being selected from the group consisting of a) at least two fluorenone alkylsulfonylphenylhydrazone groups, b) at least two fluorenone pyrrolylhydrazone groups, c) at least two fluorenone benzotriazolylhydrazone groups, d) at least two fluorenone sulfolanylhydrazone groups, e) at least two fluorenone pyrazolylhydrazone groups, f) at least two fluorenone naphthylhydrazone groups, g) at least two fluorenone tetrazolylhydrazone groups, h) at least two fluorenone stilbenylhydrazone groups, and i) at least two fluorenone (9H-fluoren-9-ylidene)benzylhydrazone groups. Some of these fluorenones may be represented by the formula
where n is an integer between 2 and 6, inclusive; R1 is hydrogen, an alkyl group, or an aryl group (e.g., phenyl, naphthyl, stilbenyl, benzyl, or tolanyl group); R2 is an alkylsulfonylphenyl or one of its derivatives; X is a linking group having the formula -(CH2)m-, branched or linear. The compounds may form electrostatic imaging systems in combination with
(b) a charge generating compound; and
(c) an electrically conductive substrate.
本发明涉及一种新型有机光感受器,包括:(a)至少一种带有不同基团的芴酮腙电荷传输材料,所述基团的组合选自以下组合:a)至少两个芴酮烷基磺酰基苯基腙基团;b)至少两个芴酮吡咯基腙基团;c)至少两个芴酮苯并三唑基腙基团;d)至少两个芴酮磺酰基苯基腙基团;e)至少两个芴酮吡唑基腙基团;f)至少两个芴酮萘基腙基团;g)至少两个芴酮四唑基腙基团;h)至少两个芴酮苯乙烯基腙基团;i)至少两个芴酮(9H-芴-9-基)苄基腙基团。其中,这些芴酮可以用以下公式表示:其中n为2至6之间的整数;R1为氢、烷基或芳基(例如苯基、萘基、苯乙烯基、苄基或甲苯基);R2为烷基磺酰基苯基或其衍生物之一;X为具有以下式的连接基,分支或线性。这些化合物可以与(b)电荷生成化合物和(c)电导基板组合形成静电成像系统。
