Three new topology-varied rod-coil block copolymers, comprising the same oligo(p-phenyleneethynylene) (OPE) rod components and the same coil components, were synthesized by atom-transfer radical polymerization. Their photophysical properties were systematically studied and compared in consideration of their solid-state structures and self-assembly abilities. These copolymers have similar intrinsic photophysical
通过原子转移自由基聚合反应合成了三种新的拓扑变化的杆-线圈嵌段共聚物,它们包含相同的低聚(对亚苯基亚乙炔基)(OPE)杆组分和相同的线圈组分。考虑到它们的固态结构和自组装能力,对它们的光物理性质进行了系统地研究和比较。这些共聚物在稀释溶液中具有与OPE棒相似的固有光物理性质。然而,它们的固态光物理性质被超分子组织操纵而相异。广角X射线衍射(WAXD)和原子力显微镜(AFM)数据表明,由于棒的分子结构依赖性pi-pi相互作用,这些共聚物具有不同的自组装能力。因此,
