requirement for cellular imaging and other biological applications. The anticancer drug cisplatin is used as a model, and is linked to polythiophene to obtain a conjugate ‘PT–Pt’ by coordinated interactions between cisplatin and the amine groups of the polythiophene side chain. The PT–Pt can be used for monitoring the cellular distribution of cisplatin by fluorescence microscopy. The amphiphilic polythiophene
通过铃木偶联反应合成了一种新的两亲性共轭聚噻吩衍生物(PT–Boc)。两亲特性使其在水中形成纳米聚集体,其中疏水性部分汇聚在一起形成内核。该聚合物即使在高浓度(100μgmL -1)下也显示出良好的光稳定性,并且对人肺上皮(A549)细胞无毒性。因此,它满足了细胞成像和其他生物学应用的关键要求。以抗癌药顺铂为模型,通过顺铂与聚噻吩侧链的胺基团之间的协同相互作用,将聚噻吩与聚噻吩连接以获得缀合物“ PT-Pt”。该PT-铂可用于通过荧光显微镜监测顺铂的细胞分布。两亲性聚噻吩为活细胞中药物和生物分子的荧光成像提供了平台。
