  Kinetic resolution of racemic sulphoxides by chiral poly[N-(1-phenylethyl)iminoalanes](PIA-PHETs) from (+)- or (–)-1-phenylethylamine is described. For p-tolyl mesityl sulphoxide in the temperature range between –25 and +85 °C, optical yields increase with temperature to an upper limit of between 55 and 70 °C, with enantiomeric enrichments up to ca. 75%. It is shown that, among the three molecular

  描述了由（+）-或（-）-1-苯基乙胺中的手性聚[ N-（1-苯基乙基）亚氨基丙氨酸]（PIA-PHETs）消旋亚砜的动力学拆分。对于p -甲苯基三甲苯基砜在-25和85℃之间的温度范围，光学收率随着温度增加至55和70之间上限℃，用对映体富集高达CA。75％。结果表明，在PIA-PHET的三个分子种类（闭笼四聚体，闭笼六聚体和开笼四聚体）中，只有最后一个具有化学活性并能够进行手性识别。反应遵循二级动力学（在亚砜中一级，在开放式PIA-PHET四聚体中一级）。后者的特定分子结构可能解释了高温下手性的高度识别。

  The present invention relates to photo-tunable dopant compositions comprising a photo-reactive chiral compound capable of undergoing a photochemical reaction resulting in the loss of chirality, and a triplet sensitizer. The present invention also relates to a display comprising a substrate, a liquid crystalline layer thereon, wherein the liquid crystalline layer comprises a nematic host, at least one chiral dopant, a photo-reacted compound, and a triplet sensitizer, and at least one transparent conductive layer. The present invention also relates to a method of tuning a cholesteric liquid crystal material comprising providing at least one mesogenic compound, at least one triplet sensitizer, and at least one photo-reactive chiral compound; combining the at least one mesogenic compound, at least one triplet sensitizer, and at least one photo-reactive chiral compound to form a mixture; and irradiating the mixture for a period of time.
