  organocatalyst, graft polymer supported dimethylaminopyridine (g‐DMAP), is developed. This catalyst has a flexible structure and comprises DMAP anchored to the polyethylene‐graft‐polyacrylic acid (PE‐g‐PAA). It exhibits higher activity than DMAP supported on polystyrene cross‐linked with divinylbenzene and can be recovered in batch mode acetylation. The activity and stability of this catalyst allow its application

  开发了一种新的非均相有机催化剂，接枝聚合物负载的二甲基氨基吡啶（g- DMAP）。该催化剂具有灵活的结构，并包含锚固在聚乙烯接枝聚丙烯酸（PE- g- PAA）上的DMAP 。它显示出比在与二乙烯基苯交联的聚苯乙烯上支撑的DMAP更高的活性，并且可以分批方式乙酰化回收。该催化剂的活性和稳定性使其可用于连续流系统。连续乙酰化可实现出色的转化率，使用g可以实现560的周转率‐DMAP。平行固定床反应器用于扩大该连续流系统的合成。八个平行的固定床反应器显示出优异的转化率。

  The present invention relates to use of liquid crystal material (30) encapsulated in a containment medium (33) to produce a controlled colored output, for example, in response to the application, removal and variation in an electric field. In one embodiment a non-pleochroic dye (9) is in the containment medium (33) itself and in another embodiment the non-pleochroic dye (9) is in the liquid crystal material (30) itself; and in both cases the dye (9) preferably is fluorescent or a combination of fluorescent and non-­fluorescent, and the object is to color light and/or to whiten or to brighten the light emitted out from a display (10) embodying the invention. Incident light (17) impinging on the encapsulated liquid crystal material (30), which is mounted on, in, or with respect to a support medium (12), is isotropically scattered in the absence of an electric field, and using the principle of total internal reflection (or optical interfence or both) a relatively large part of the isotropically scattered light in the support medium (12) is reflected back to illuminate the scattering liquid crystal material (30), which isotropically scatters such light again, thus increasing the optical path through the dyed material (9) and, therefore, the coloring, whitening and/or brightening of the light traveling such increased path. Light scattered back to the viewing direction out of the support medium (12) causes the liquid crystal material (30) to appear relatively bright and colored as compared to the background where there is no liquid crystal material or where the liquid crystal material is in parallel alignment in field-on condition, i.e. aligned with respect to an electric field, and, thus, substantially transmissive.

  本发明涉及使用封装在封装介质（33）中的液晶材料（30）来产生受控的彩色输出，例如，响应电场的应用、移除和变化。在一个实施例中，非pleochroic染料（9）在封装介质（33）本身中，在另一个实施例中，非pleochroic染料（9）在液晶材料（30）本身中；在这两种情况下，染料（9）最好是荧光的或荧光和非荧光的组合，目的是使光着色和/或使从体现本发明的显示器（10）发出的光变白或变亮。入射光（17）照射到安装在支撑介质（12）上、支撑介质（12）内或相对于支撑介质（12）的封装液晶材料（30）上，在没有电场的情况下会发生各向同性散射，利用全内反射原理（或光学界面原理或两者兼而有之的原理），支撑介质（12）中相对较大部分的各向同性散射光被反射回来，照亮散射液晶材料（30）、这部分光再次被等向散射，从而增加了通过染色材料 (9) 的光路，并因此增加了光路的着色、增白和/或增亮效果。从支撑介质 (12) 散射回观察方向的光会使液晶材料 (30) 显得相对明亮，与没有液晶材料的背景或液晶材料在场上平行排列的背景（即相对于电场排列）相比，液晶材料 (30) 显得相对彩色，因此基本上是透射的。

  Encapsulated liquid crystal material (61) in a support medium illuminated from the viewing side (20) or direction or through a louvered light guide (143) from the back side will appear bright or white relative to background when in distorted alignment, e.g. in the absence of an electric field. Incident light impinging on the liquid crystal material (61) is isotropically scattered into the support medium, and using the principle of total internal reflection and possibly also optical interference a relatively large part of the isotropically scattered light is directed back to illuminate the distorted liquid crystal material (61) tending to brighten the same so that light it scatters back to the viewing direction (20) out of the support medium causes the liquid crystal material (61) to appear relatively light or bright as compared to the background where there is no light crystal material (61) or where the liquid crystal material (61) is in parallel alignment in field-on condition, i.e. aligned with respect to an electric field, and, thus, substantially transmissive. Original incident light where there is no liquid crystal material (61 that light which is isotropically scattered toward the back or non-viewing side of the display (140) and within a certain cone or solid angle, and that light passing through aligned (field-on) liquid crystal material (61) will tend not be be totally internally reflected; such light will pass through the support medium and may be absorbed by a remote black or colored material (144).

  支持介质中的封装液晶材料（61）从观察侧（20）或方向或通过百叶导光板（143）从背面照射，在扭曲排列时，例如在没有电场的情况下，相对于背景会显得明亮或白色。照射到液晶材料 (61) 上的入射光会各向同性地散射到支撑介质中、利用全内反射原理，也可能利用光干涉原理，各向同性散射光中相对较大的部分被引导回来，照亮扭曲的液晶材料 (61)，使其变亮，从而使其从支持介质中散射回观察方向 (20) 的光使液晶材料 (61) 相对于没有液晶材料 (61) 的背景或液晶材料 (61) 在场上平行排列的背景（即相对于电场排列）显得相对较亮或较亮。即相对于电场对齐，因此基本上是透射的。在没有液晶材料（61）的情况下，原始入射光会在一定的锥角或实角范围内向显示屏（140）的背面或非观察侧等向散射，穿过对齐（场致）液晶材料（61）的光往往不会被完全内部反射；这些光会穿过支撑介质，并可能被远处的黑色或彩色材料（144）吸收。
