双光轴偶氮液晶(biaxialnematicazoliquidcrystal)具有光致异构特性、良好的稳定性和可逆性等优点,可通过结构修饰和外部电场控制进一步提高材料性能,从而降低写入激光波长,提高稳定温度和反应速度,在高密度光学存储材料中具有极大的潜在应用价值。综述了双光轴偶氮液晶分子光致异构机理的近期研究结果,分析了它对偏振光选择吸收时发生顺反循环异构的动力学过程,展示了其实际应用。
Biaxial nematicazoliquid crystal has the advantages of photoisomerization, good stability and reversibility, and can further improve the material properties through structure modification and external electric field control, so as to reduce the write laser wavelength, increase the stable temperature and The reaction rate has great potential applications in high-density optical storage materials. Recent research results on the mechanism of photoisomerization of biaxial azo liquid crystal molecules are reviewed. The kinetics of cis - and counter - cyclic isomerism when selective absorption of polarized light is analyzed, and its practical application is also demonstrated.
