摘要

带有适当悬饰的聚烯烃可以形成稳定的螺旋,并表现出显著的光学活性。这些螺旋多烯含有可进一步官能化的活性双键,是一类具有广阔应用前景的手性功能材料。这篇综述文章深入探讨了通过受控合成方法合成定义明确的螺旋多烯的复杂性,包括螺旋感应选择性活聚合、区域选择性和不对称活聚合,以及烯与芳基单体的一锅嵌段共聚。系统概述了由此产生的螺旋聚烯和相关共聚物的特点,包括其独特的光电性质、刺激响应性、螺旋诱导的手性自组装和圆偏振发光(CPL)。此外,还详细讨论了螺旋聚烯的可控合成、功能性和应用研究目前面临的挑战和未来前景。

Helical Polyallenes: From Controlled Synthesis to Distinct Properties.

Polyallenes with appropriate pendants can form stable helices and exhibit significant optical activity. These helical polyallenes contain reactive double bonds that allow for further functionalization, making them a class of chiral functional materials with broad application prospects. This review article delves into the intricacies of synthesizing well-defined helical polyallenes through controlled synthetic methodologies, including helix-sense selective living polymerization, regioselective and asymmetric living polymerization, and one-pot block copolymerization of allenes with aryl monomers. The systemically outlined characteristics of the resulting helical polyallenes and related copolymers are summarized include their unique chiroptical properties, stimuli-responsiveness, helix-induced chiral self-assembly, and circularly polarized luminescence (CPL). Additionally, current challenges and future perspectives in the research of controlled synthesis, functionalities, and applications of helical polyallenes are discussed in detail.
