Abstract

A good turn: Three compounds that bear two axially chiral bridged binaphthyl units were developed as photodynamic chiral dopants for nematic liquid crystals. For compounds with suitable bridge lengths, a change in the dihedral angle induced a switch of the binaphthyl units from the cisoid to the transoid form upon UV irradiation, which led to an inversion of the handedness of the helices.

摘要

善举

三种含有两个轴向手性桥联联萘基单元的化合物被开发为手性近晶相液晶的光致动力学手性掺杂剂。对于具有合适桥接长度的化合物，在紫外光照射下，二面角的变化导致联萘基单元从顺式构型向反式构型转变，从而导致螺旋手性的反转。
