Abstract

In the polymerization-induced chiral self-assembly (PICSA) process, chiral functional monomers undergo spontaneous supramolecular self-assembly and asymmetric stacking during living polymerization, leading to the in situ generation of chiroptical polymer assemblies characterized by diverse morphologies. The PICSA strategy facilitates precise control and manipulation of both non-covalent supramolecular helices and covalent macromolecular helices within aggregated cores, thereby driving significant advancements in fields such as chiral recognition materials, asymmetric catalysts, nonlinear optical materials, and ferroelectric liquid crystals (LC). This minireview summarizes recent developments in the in situ chiroptical construction and modulation associated with the PICSA methodology. Furthermore, it seeks to elucidate emerging PICSA systems founded on various living polymerization mechanisms, exploring hierarchical chirality transfer processes and the pathway complexities in both equilibrium and non-equilibrium conditions. This minireview also presents several illustrative examples that demonstrate the practical applications of chiral polymer materials synthesized through the PICSA approach, thereby illuminating future opportunities in this innovative field.

聚合诱导手性自组装,用于不对称超结构的原位构建、调制、放大和应用。
在聚合诱导手性自组装(PICSA)过程中,手性功能单体在活体聚合过程中发生自发超分子自组装和不对称堆积,从而在原位生成具有不同形态特征的手性聚合物组装体。PICSA 策略有助于精确控制和操纵聚合核心内的非共价超分子螺旋和共价大分子螺旋,从而推动手性识别材料、不对称催化剂、非线性光学材料和铁电液晶等领域的重大进展。本微型综述总结了与 PICSA 方法相关的原位自旋构造和调制的最新进展。此外,它还试图阐明建立在各种活聚合机制基础上的新兴 PICSA 系统,探索分层手性转移过程以及平衡和非平衡条件下的复杂路径。本小视还介绍了几个实例,展示了通过 PICSA 方法合成的手性聚合物材料的实际应用,从而揭示了这一创新领域的未来机遇。
