  Design of photonic liquid crystal materials: synthesis and evaluation of new chiral thioindigo dopants designed to photomodulate the spontaneous polarization of ferroelectric liquid crystals

  摘要：

  由光致变色掺杂物 (R,R)-6,6′-bis(2-octyloxy)-5,5′-dinitrothioindigo 和 (R,R)-5,5′-dichloro-6,6′-bis(2-octyloxy)thioindigo 在波长 λ=514 和 532 nm 下照射，引起了铁电 S C * 液晶相自发极化 (P S ) 的增加，增幅范围从 1.4 到 4.0。P S 的这种增加是在不伴随 S C * 相不稳定化的情况下实现的，且与因顺-反光异构化导致的硫靛核心的横向偶极矩增加相一致。硫靛核心对 P S 的贡献是通过与手性侧链的立体极化耦合实现的，该耦合在硝基和氯取代基的存在下得到了增强。
