由2，6-二（（三甲基硅基）乙炔基）BODIPY的“一锅法”氧化偶联反应合成了一系列均匀的含有多达四个BODIPY部分的定义明确的丁二炔基-BODIPY低聚物。所得BODIPY二聚体的进一步衍生产生具有吡啶离子的水溶性的、发红光的丁二烯连接的BODIPY二聚体，其可以基于两种荧光构象异构体（其中两个BODIPY核根据环境的粘度彼此扭曲且平面）按比例检测粘度。
A homogeneous series of well-defined butadiynylene-BODIPY oligomers containing up to four BODIPY moieties have been synthesized from a “one-pot” oxidative homocoupling reaction of 2,6-di((trimethylsilyl)ethynyl)BODIPY. Further derivation of the resultant BODIPY dimer generates a water-soluble, red-emitting butadiyne-linked BODIPY dimer with pyridinium ions, which can ratiometrically detect viscosity, based on the two fluorescent conformers with the two BODIPY cores twisted and planar to each other depending on the viscosity of the environment.
