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。

The UV and IR spectroscopic studies of the monomer films showed that the photoreaction ratio of monomer (about 50%) was higher than the corresponding photosensitive polymer (about 10%, PVCi). The polarized IR spectra proved that obvious anisotropic absorption was displayed in the irradiated photosensitive film. With polarizing microscopy method, we found that these kinds of photoalignment films exhibited good alignment ability, and the stability of the photoalignment film could reach about 100℃. 2 A photosensitive self-assembled monolayer was fabricated that contained photo-cycloadditable groups, such as, coumarin and cinnamate. The reaction process were detected by contact angle method because the IR absorption of monolayer was very weak. The photosensitive self-assembled monolayer promote uniform alignment of nematic liquid crystals by LPUV, and it thermal stability could reach about 130℃. 3 A cationic bolaform amphiphiles was synthesized that had two photosensitive double bonds, and can be polymerized by ultraviolet. A layer-by-layer self-assembled deposition film was prepared in aqueous solution by using this material and poly (sodium 4-styrenesulfonate). The UV-Vis. spectra proved that the multilayers film was uniform and layer-by-layer. When LPUV irradiated the film, the photopolymerizable double bond underwent [2+2] cycloaddition, and the production of the reaction distributed along the polarized direction of incident LPUV. Polarized UV-Vis. spectra indicated that the irradiated self-assembled multiplayer film was anisotropic, and the dichromic ration is about 0.09, it is higher than the spin-coating method of photosensitive polymer or monomer. We used this anisotropic film as alignment layer of nematic liquid crystals, and obtained a uniform and stability alignment result, the static contrast ratio is about 100, which is very close to application of liquid crystal device. This thesis is an instance that the photochemical material was used in the physics region of liquid crystals, the route that was from photosensitive monomer, self-assembled monolayer film to self-assembled multiplayer film was undergone, by this logical research method photoailgnment of liquid crystal was extended and consummated.
