多组分掺杂单层结构有机光导体研究

Study on a single-layered multi.components photoreceptor

研究以联苯醌衍生物作为电子传输材料（ETM）与空穴传输材料（HTM）、电荷产生材料（CGM）和成膜树脂进行匹配，制备了三组分掺杂和双组分掺杂的单层结构有机光导体，系统地研究了电荷传输材料对单层结构有机光导体静电照相性能的影响。研究结果表明，光导体的的半衰曝光量对电子传榆材料的掺杂浓度具有强烈的依赖性，半衰曝光量首先随ETM浓度的增大而减小，在780nm处，三组分掺杂光导体最低半衰曝光量为2．2μJ／cm（正充电），负充电半衰曝光量为2．8μJ／cm（负充电）：双组分掺杂正充电光导体的半衰曝光量为0．59μJ/cm^2，负充电光导体的半衰曝光量为9．6μJ／cm^2。

This paper reports on a single-layered multi-components photoreceptor, which was a polymer matrix doped with charge generation material （CGM）, electron transport material （ETM） and hole transport material （HTM）. At the present stage, a series of diphenoquinone derivatives were used as ETM. It was found that photosensitivity was strongly dependent on ETM concentration. The half decay exposure decreased with ETM＇s concentration. For tercomponent single-layered organic photoreceptor, the lowest half decay exposures of positive- and negative-charging were 2.2 and 2.8μJ/cm^2 at 780nm wavelength, respectively. And for bicomponent single-layered organic photoreceptor, the lowest half decay exposures of positive- and negative-charging were 0.59 and 9.6μJ/cm^2 at 780nm wavelength.
