摘要以四苯基乙烯（TPE）为基础，利用著名的AIE活性基团TPE单元，通过“A2+B4”的方法，采用一锅铃木缩聚反应，与其他3个芳基嵌段构建了超支化聚合物，以开发新型四苯基共轭超支化聚合物。这三种超支化聚合物表现出有趣的AIEE行为，在纳米颗粒和固体状态下都具有高灵敏度的爆炸化学传感器。本文首次报道了基于tpe的共轭超支化聚合物的AIE活性。其相应的PLED器件也表现出良好的性能。
With the aim to develop new tetraphenylethylene (TPE)-based conjugated hyperbranched polymer, TPE units, one famous aggregation-induced emission (AIE) active group, are utilized to construct hyperbranched polymers with three other aromatic blocks, through an "A2+B4" approach by using one-pot Suzuki polycondensation reaction. These three hyperbranched polymers exhibit interesting AIEE behavior and act as explosive chemsensors with high sensitivity both in the nanoparticles and solid states. This is the first report of the AIE activity of the TPE-based conjugated hyperbranched polymers. Their corresponding PLED devices also demonstrate good performance.
