Exploring the generation and transfer of chirality at different hierarchical levels has always been a significant research subject. The present contribution reports our success in inducing and regulating the helical chirality of achiral macromolecules (racemic polyacetylene) by using a chiral helical macromolecule (chiral polylactide); helical chirality is sufficiently transferred between two types of helical polymer chains. Hydrogen bonds are demonstrated to play a crucial role in the chirality transfer process. More interestingly, the induced helical chirality can be further transferred to additionally added achiral fluorophore molecules, thereby leading to the emission of full-color and white circularly polarized luminescence (CPL). The present study opens up an unprecedented two-step chirality transfer process to realize both the generation of helical chirality in achiral polymers and full-color CPL emissions in achiral fluorescence compounds.

手性聚丙交酯调控外消旋聚乙炔的螺旋手性实现全彩色和白色圆偏振发光

探索不同层次的手性的产生和转移一直是一个重要的研究课题。目前的贡献报告了我们通过使用手性螺旋大分子（手性聚丙交酯）成功诱导和调节非手性大分子（外消旋聚乙炔）的螺旋手性；螺旋手性在两种类型的螺旋聚合物链之间充分转移。氢键被证明在手性转移过程中起着至关重要的作用。更有趣的是，诱导的螺旋手性可以进一步转移到额外添加的非手性荧光团分子，从而导致发射全色和白色圆偏振发光（CPL）。
