modified with gold nanoparticles were synthesized and characterized using a different mode of delegated tools e.g. FTIR, NMR and FESEM–EDX measurements for the structural properties of synthesized compounds. Polarized optical microscopy studies have revealed all the studied compounds having liquid crystalline properties, as a typical nematic phase. These liquid crystal capped gold nanoparticles' size was
合成了一系列用金纳米粒子改性的新型基于偶氮苯的硫醇化液晶,并使用不同的委托工具模式(例如FTIR,NMR和FESEM-EDX测量)对合成化合物的结构特性进行了表征。偏振光学显微镜研究已经揭示了所有具有液晶性质的研究化合物,作为典型的向列相。这些液晶覆盖的金纳米颗粒的尺寸通过TEM实验确定。另外,含有柔性间隔基的基于偶氮苯的金纳米颗粒在紫外线照射下表现出光致变色行为。这些分子在溶液中表现出很强的光异构化行为,并且可以反式转化为顺式 异构化大约需要44 s,而反向过程几乎发生了82至125分钟。
