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.

I stacked blocks, made squadrons of paper airplanes, lined up toy soldiers, watched the "Three Stooges," planted corn kernels in paper cups, read comic books, tended my coin and stamp collections, counted baseball cards, painted shells I'd collected at the Jersey shore, picked at my guitar, wrestled with my brother, allowed my pet turtle to walk up my arm, teased the cat with string, brushed my hair in a funny way, made hand puppets out of paper bags - and this is just my short list.

除了这些，我还堆积木，用纸折飞机组成飞行中队，给玩具士兵列队，坐在电视机前看《活宝三人行》，把吃完的玉米棒插进纸杯里，看漫画，收集硬币和邮票，收集棒球卡片，给我在泽西海滩收集的贝壳上色，学了一点点吉他，跟我哥哥摔跤，让我的宠物龟爬上我的胳膊，用毛线逗小猫，梳过怪异的发型，用纸袋制作了手指木偶：这还只是我儿时活动清单的一小部分。
