Access to diverse, relatively high molecular weight soluble linear polymers without pendant solubilizing chains is the key to solution state synthesis of structurally diverse nanoribbons of conjugated materials. However, realizing soluble 1D-π-conjugated polymers without pendant solubilizing chains is a daunting task. Herein, inspired from the polypeptide β-strand architecture, we have designed and developed novel bifacial π-conjugated polymers ( : 24 kDa) that are soluble ( 70 to >250 mM) despite the absence of pendant solubilizing chains. The impact of varying the bifacial monomer height on polymer solubility, optical properties, and interactions with small molecules is reported.
获得没有侧链增溶链的各种相对高分子量的可溶性线性聚合物是共轭材料结构多样的纳米带溶液状态合成的关键。然而,实现没有侧链增溶链的可溶性一维π共轭聚合物是一项艰巨的任务。在此,受多肽β链结构的启发,我们设计并开发了新型的双面π共轭聚合物(:24 kDa),尽管没有侧链增溶链,但它们是可溶的(70至>250 mM)。报道了改变双面单体高度对聚合物溶解度、光学性质以及与小分子相互作用的影响。
