以2-双（五氟苯基）硼基偶氮苯为原料，与碘甲烷或丙磺酸内酯进行季铵化反应，合成了水溶性荧光偶氮苯。2-硼基偶氮苯在水中溶解并发出荧光。离子部分的双重引入使偶氮苯具有更高的水溶性。动态光散射和扫描电子显微镜测量表明，2-硼偶氮苯聚集在水中。它们有望应用于水性环境。
Water-soluble fluorescent azobenzenes have been synthesized by quaternization of 2-[bis(pentafluorophenyl)boryl]azobenzenes bearing dimethylamino groups with iodomethane or propanesultone. The 2-borylazobenzenes both dissolve and fluoresce in water. The double introduction of ionic moieties provides the azobenzenes with higher water solubility. Dynamic light scattering and scanning electron microscopy measurements indicate that the 2-borylazobenzenes aggregate in water. They are expected to be applied in aqueous environments.
