  light caused trans→cis isomerization of BMAB, which induced simultaneously the nematic (N)→isotropic phase transition of the PLC films. This photochemically induced phase transition was reversible and photoirradiation with a 525 nm light which induced cis→trans isomerization restored the system to the initial phase (N). The photo-induced phase transition was found to be strongly dependent on molecular

  已在聚合物液晶 (PLC) 中证明了放大光学图像存储。将少量 (< 5 mol%) 具有光响应性部分的低分子量介晶 4-丁基-4'-甲氧基偶氮苯 (BMAB) 掺杂到具有介晶侧链聚 (4'-甲氧基苯基) 的聚丙烯酸酯薄膜中-4-丙烯酰氧基烷氧基苯甲酸酯)(PAn)，其中烷基间隔长度 (CH2)n 随 n = 2、3、5 和 6 变化。用 366 nm 光照射 PA3/BMAB 膜导致反式→顺式异构化BMAB，它同时诱导了 PLC 薄膜的向列 (N)→各向同性相变。这种光化学诱导的相变是可逆的，用 525 nm 光进行光照射会诱导顺式→反式异构化，使系统恢复到初始相 (N)。

  solution by femtosecond transient absorption and picosecond single-photon timing fluorescence spectroscopies. The fluorescence was observed at 400 nm with a lifetime ∼250 fs. The S1 state with an absorption maximum at 410–415 nm was formed with a time constant of ∼250 fs from the S2 state followed by relaxation with a lifetime of ∼2.3 ps in n-hexane. The stimulated emission from the S2 state overlapped

• Photochemical Control of Properties of Ferroelectric Liquid Crystals. 2. Effect of the Structure of Guest Photoresponsive Molecules on the Photochemical Switching of Polarization
  作者：Takeo Sasaki、Tomiki Ikeda

  DOI：10.1021/j100034a047

  日期：1995.8

  The photochemical switching of polarization of ferroelectric liquid crystals (FLCs) was investigated for various structures of guest photoresponsive molecules. The structure of the photoresponsive molecules affected significantly the efficiency of inducing the switching of polarization. It was found that azobenzenes with a structure similar to the host FLC induced the photochemical switching of polarization quite effectively.
