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.

对蒽醌系列偶氮染料光敏性的研究结果表明，偶合基酰胺芳环上的基团会影响其光敏性，并随吸电子性质的增强光敏性增加，首次揭示了其光敏性与Hammett常数σ间有良好线性关系的规律。

The pigments synthesized from 2, 7-diaminoflurenone consistently show better photosensitivity than that containing anthraquinone. A plot of the E1/2 values against the Hammett constant σ was obtained for the pigments which have different substituents in the anilide ring. The plot reveals that neither a strong electron-releasing group, such as methoxy, nor a electron-withdrawing group, such as nitro-group, enhances the sensitivity of the photoreceptor in which these pigments are used as CGL materiel.

芴酮类偶氮染料的光敏性优于蒽醌类偶氮染料，其偶合基酰胺芳环取代基为强的给电子基团或强的吸电子基团时都不利于其光敏性的提高，只有当取代基基团为氯时其表现出最好的光敏性，这一结果与Law等人的研究结果相同。

Based on the possible degradation products, Microbial degradation pathways of metsulfuron-methyl is concluded as follows: after the cleavage of the sulfonylurea bridge, 2-amino-4-methoxy-6-methyl-triazine is demethylated and the annularity reaction of sulphanilamide occurs.
