共轭梯形聚合物(CLP)是一种由周期性重复的稠环组成的大分子。它们的刚性和完全共轭的骨架赋予了CLP有趣的光学、电子和磁性特性。目前CLP化学面临的挑战是，由于不利的副反应(如交联和支化)和它们的低溶解度，很难控制它们的合成。模板受限合成是一种在原子尺度上控制CLP结构的可行策略。在这篇综述中，我们描述了利用模板合成CLP的最新进展和未来的前景，模板包括金属表面和纳米孔材料。获得具有更大多样性的CLP将有助于控制其固有特性，为其未来在许多领域的应用铺平道路。
Conjugated ladder polymers (CLPs) are an attractive type of macromolecule consisting of periodically repeated fused aromatic rings. Their rigid and fully conjugated backbones endow CLPs with intriguing optical, electronic, and magnetic properties. Current challenges facing CLP chemistry are difficulty in regulating their synthesis due to unfavorable side reactions (e.g. cross-linking and branching) and their low solubility. Template-confined synthesis is a viable strategy for controlling CLP structures at the atomic scale. In this review, we describe recent developments and future perspectives in the confined synthesis of CLPs utilizing templates, including metal surfaces and nanoporous materials. Access to CLPs with greater diversity will contribute to the ability to control their intrinsic properties, paving the way to their future applications in many fields.
