  Photoresolution of an Axially Chiral Bicyclo[3.2.1]octan-3-one: Phototriggers for a Liquid Crystal-Based Optical Switch

  摘要：

  The axially chiral ketones 8-(phenylmethylene)bicyclo[3.2.1]octan-3-one (1) and 3-(phenylmethylene)bicyclo[3.2,1]octan-8-one (2) were prepared and investigated for suitability as a chiroptical trigger in a liquid crystal-based optical switch. Irradiation of optically active ketone 1 with unpolarized light leads to its efficient photoracemization. Its irradiation with circularly polarized light leads to partial photoresolution with an enantiomeric excess sufficient for it to function as a chiroptical trigger. However, 1 is not sufficiently soluble in ZLI-1167, a nematic liquid crystalline material, to induce a measurable pitch. Ketone 2 is unstable to irradiation and is not suitable for use as a chiroptical trigger.

• Investigation of Bicyclic Thioketones as Triggers for Liquid Crystal Optical Switches
  作者：Rochelle Fisher Bradford、Gary B. Schuster

  DOI：10.1021/jo0264675

  日期：2003.2.1

  The axially chiral bicyclic thioketones 11 and 15 were prepared and investigated for suitability as chiroptical triggers in a liquid crystal optical switch. Irradiation of partially resolved 15 with unpolarized light leads to its conversion to the racemic form (photoracemization). However, irradiation of racemic thioketones 11 and 15 with circularly polarized light does not lead to detectable photoresolution

  制备了轴向手性双环硫酮11和15，并研究了其在液晶光学开关中作为手性触发剂的适用性。用非偏振光照射部分分解的15会导致其转换为外消旋形式（光消旋）。然而，用圆偏振光照射外消旋硫酮11和15不会导致可检测的光分辨率。缺乏光分辨率的原因是分子内键合三重态能量转移效率低下。这些硫酮不适合用作光触发。
