Bistriazole benzo[1,2-b:4,3-b′]dithiophene (BDT) contained bolaamphiphiles have been synthesized via Sonogashira coupling and click reactions as key steps. For such compounds, the central bent bistriazole BDT core, the flexible methylene spacer led the rodlike core together with the terminal diol groups to twist to be U-shaped polar region. Micro-segregation of U-shaped polar region from the lipophilic
通过Sonogashira偶联和点击反应作为关键步骤合成了含有双三唑的苯并两亲物苯并[1,2-b:4,3-b']二噻吩(BDT)。对于此类化合物,中心弯曲的双三唑BDT核,柔性亚甲基间隔基将杆状核与末端二醇基团一起扭曲成U形极性区域。U形极性区域从亲脂链的微分离产生了SmA相。此外,这些化合物还可以充当超级有机胶凝剂,以0.2 mg / ml的最低临界胶凝浓度(CGC)胶凝各种溶剂。首先在亲两亲性自组装系统中观察到几乎没有报道的包括纳米纤维,纳米带,纳米盘,纳米小管和纳米管在内的凝胶形态。
