The results also show the sensitivity is enhanced for the pigments with a larger anilide ring. It is important to note that the photosensitivity is greatly increased when the coupler component changed ftom a 2-hydroxy-3-naphthanilide to a 2-hydroxy-11H-benzocarbazole-3-naphthanilide coupler. Clearly, conjugation effects favours to enhance the photosensitivity.

偶合基部分共轭环的扩大使蒽醌偶氮染料的光敏性增加，特别是偶合基萘环上扩大了一个咔唑环后，其吸收光谱大幅红移，光敏性提高了几十倍，这一结果对红外偶氮光导染料的设计合成具有重要参考价值。

The photoconductive properties of the pigments containing anthraquinone are studied in bilayer photoreceptor. A linear relationship between pigments that bear a substituent in the anilide ring in the coupler moiety and Hammett constant σ was obtained. Therefor, we conclude that electron-withdrawing groups enhances the sensitivity of these pigments.
