摘要

近年来，具有明确原子级别结构的单晶聚合物引起了广泛关注。精确的结构信息对理解聚合物排列方式、分子间相互作用、结构—性能关系至关重要。目前，制备大尺寸单晶聚合物的方法仍然是高分子合成领域面临的关键挑战。拓扑化学聚合因其无溶剂、高区域选择性等特点，能实现单体单晶到聚合物单晶的直接转化，是制备单晶聚合物的有效途径。本综述系统总结了近年来拓扑化学聚合在构筑单晶聚合物方面的研究进展，并基于反应类型对典型体系进行了归纳，重点讨论了如[2+2]环加成、[4+4]环加成、二炔/三炔聚合及其他晶格约束反应的结构特征、反应条件及适用范围。此外，汇总了具有明确结构信息的代表性单晶聚合物实例，同时对单晶聚合物的潜在应用领域、发展机遇和挑战进行了简单探讨。

Abstract

In recent years

single-crystal polymers with well-defined atomic-level structures have attracted considerable attention. Precise structural information is crucial for understanding polymer arrangement

intermolecular interactions

and structure-property relationships. The preparation of large single-crystal polymers remains a key challenge in polymer synthesis. Topochemical polymerization

owing to its solvent-free nature and high regioselectivity

enables the direct conversion of monomer crystals to polymer single crystals

providing an effective approach for the preparation of single-crystal polymers. This review systematically summarizes recent advances in topochemical polymerization for constructing single-crystal polymers

categorizing typical systems based on reaction types. The structural features

reaction conditions

and applicability of reactions such as [2+2] cycloaddition

[4+4] cycloaddition

diyne/triyne polymerization

and other lattice-constrained reactions are discussed in detail. Additionally

this paper presents a summary of representative single-crystal polymer examples with well-defined structural information and briefly explores the potential application fields

development opportunities

and challenges of single-crystal polymers.
