Anchoring properties of photoaligned azo-dye materials.
The photoinduced alignment of a liquid crystal (LC) on films of azo dyes was studied for the liquid crystal display applications. In order to improve the alignment stability of the photoaligned dye (SD-1), the azo-dye derivative with polymerizable terminal groups was synthesized (SDA-1). The films of SDA-1 exhibit good photoalignment properties and ultraviolet stability after thermal polymeriza...
متن کاملBile Acid Involvement in Azo Dye Carcinogenesis1
the early stages of liver carcinoma development in Sprague-Dawley rats. Bile acids were analyzed in urine and feces of azo dye-fed and control rats with the use of gas chromatography during the first 66 days of treatment. Seven bile acids were identified in the feces, with deoxycholic acid being the primary excretion product. During the first 36 days of 3'-methyl-4-dimethylaminoazobenzene feedi...
متن کاملThe cobalt(II) salt of the azo dye Orange G
Crystallizing the cobalt(II) salt of the azo dye Orange G from water was found to give the solvent-separated ion-pair species hexa-aqua-cobalt(II) 7-oxo-8-(2-phenyl-hydrazin-1-ylidene)-7,8-dihydro-naphthalene-1,3-disulfonate tetra-hydrate, [Co(H(2)O)(6)](C(16)H(10)N(2)O(7)S(2))·4H(2)O. The asymmetric unit of the cobalt(II) salt contains three independent octa-hedral [Co(OH(2))(6)](2+) cations, ...
متن کاملStudies in Carcinogenesis with Azo Compounds II. The Action of Azo Compounds in Mice, and the Bearing Thereof on Theories of Azo Dye Carcinogenesis*
The results of earlier investigations of the carcinogenic action of azo dyes in rats were summarized by Kinosita in 1937 and 1940 (22, 23), and by Hartwell in 1941 (17). Since then much work has been done involving various types of controlled, restricted diets and a theory has been evolved (19) to account for the activity of certain dyes and the inactivity of others. A short review of this work...
متن کاملDyeing of Polyester with Disperse Dyes: Part 2. Synthesis and Dyeing Characteristics of Some Azo Disperse Dyes for Polyester Fabrics.
The goal of this study was to utilize carrier for accelerating the rate of dyeing not only to enhance dyeing of polyester fabrics dyed with disperse dyes 3a,b, but also to save energy. Both the color strength expressed as dye uptake and the fastness properties of the dyed fabrics were evaluated.
