  Hydrogen bonded arylamide-linked cholesteryl dimesogenic liquid crystals: a study of the length and side chain effects

  摘要：

  Dimesogenic compounds 1a-c, 2a-i, and 3, that are composed of a hydrogen bonding-induced straight arylamide spacer and two appended cholesterol groups, have been designed and synthesized. The backbones of the rigid spacers of 1a-c, 2a-i, and 3 contain one, three, and five benzene units, which bear two, six, and ten alkoxyl (methoxyl, n-octoxyl, or n-dodecoxyl) groups, respectively. The thermal and optical properties of the compounds are investigated by using the differential scanning calorimetry (DSC), polarizing optical microscopy (POM), and powder X-ray diffraction (PXRD) analysis. It is revealed that la c exhibit one or two liquid crystalline (LC) phases, 2a-i exhibit no, one or two LC phases, while 3 exhibits one LC phase in a wide temperature range. Generally, the more and longer alkoxyl chains facilitate the formation of the LC phases at low temperature. Notably, compound 2g, which bears two methoxyl and four dodecoxyl groups, displays a blue-red color change during both the heating and cooling cycle. The result illustrates that dimesogens with large rigid spacers can exhibit different LC phases when long aliphatic chains are appended to balance the strong stacking of the rigid backbones.

  Sulfonamido dye releaser in photographic dye diffusion transfer

  摘要：

  在照片染料扩散转移过程中，使用染料给予化合物，这些化合物在照片粘合剂层中不会扩散，而在显影过程中，根据银卤化物的显影，这些化合物会在影像区域内被氧化分裂，由于显影剂组成的碱性，释放扩散染料，将其转移至图像接收层。染料给予化合物的化学式为Y--NH--Ar--NH--SO.sub.2 --X，其中ar代表芳基基团，使得Y--NH--通过n(n=1,2,3或4)个乙烯基链与--NH--SO.sub.2 --X相连接，这些乙烯基链是芳基基团的一部分；X代表染料或染料前体的基团；Y代表--COR或--SO.sub.2 R基团；R代表烷基、芳基或杂环基团，并且可以构成第二个染料基团的一部分。

  In the photographic dye-diffusion transfer process use is made of dye-giving compounds, which are non diffusing in photographic binder layers, and which during development if oxidized imagewise in accordance with the silver halide developed are split owing to the alkali of the developer composition to release diffusing dyes, which are transferred to an image-receiving layer. The dye-giving compounds have the formula Y--NH--Ar--NH--SO.sub.2 --X ar represents an arylene radical such that the group Y--NH-- is attached to the group --NH--SO.sub.2 --X through a chain of n(n=1,2,3, or 4) vinylene groups which are part of the arylene radical; X represents the radical of a dye or dye precursor; Y represents a --COR or --SO.sub.2 R radical; and R represents an alkyl, aryl or heterocyclic group and can constitute part of a second dye moiety.
