    (AACs) are highly conformation sensitive, the longest wavelength Cotton effect at 304 nm switches from Δϵ=+191 m−1 cm−1 for open (P)4‐AAC⊂acetonitrile to Δϵ=−691 m−1 cm−1 (ΔΔϵ=882 m−1 cm−1) for closed (P)4‐AAC⊂cyclohexane. Complete chiral resolution of (±)‐trans‐1,2‐dimethylcyclohexane was found in the X‐ray structures, with (P)4‐AAC exclusively bound to the (R,R)‐ and (M)4‐AAC to the (S,S)‐guest. Guest

    Purely organic shape‐persistent chiral cages are designed through the use of rigid chiral axes. Covalent dimerization of a tripodal fragment bearing chiral allenes forms a molecular twisted prism with loop‐like lateral edges presenting 10‐fold chiroptical amplification compared to its isolated building blocks. The expected geometry of covalent organic helical cage (M,M)3‐1 was confirmed by X‐ray crystal

  • Dynamic Axial‐to‐Helical Communication Mechanism in Poly[(allenylethynylenephenylene)acetylene]s under External Stimuli

    Abstract

    Helix inversion in chiral dynamic helical polymers is usually achieved by conformational changes at the pendant groups induced through external stimuli. Herein, a different mechanism of helix inversion in poly(phenylacetylene)s (PPAs) is presented, based on the activation/deactivation of supramolecular interactions. We prepared poly[(allenylethynylenephenylene)acetylene]s (PAEPAs) in which the pendant groups are conformationally locked chiral allenes. Therefore, their substituents are placed in specific spatial orientations. As a result, the screw sense of a PAEPA is fixed by the allenyl substituent with the optimal size/distance relationship to the backbone. This helical sense command can be surpassed by supramolecular interactions between another substituent on the allene and appropriate external stimuli, such as amines. So, a helix inversion occurs through a novel axial‐to‐helical communication mechanism, opening a new scenario for taming the helices of chiral dynamic helical polymers.

    摘要 手性动态螺旋聚合物中的螺旋反转通常是通过外部刺激引起悬垂基团的构象变化来实现的。本文基于超分子相互作用的激活/失活,提出了聚苯乙炔PPA)中不同的螺旋反转机制。我们制备了聚[(异戊烯乙炔亚苯基)乙炔](PAEPAs),其中的悬垂基团是构象锁定的手性异戊烯。因此,它们的取代基被置于特定的空间方向。因此,PAEPA 的螺旋感是由与骨架具有最佳尺寸/距离关系的芳基取代基固定的。这种螺旋感指令可以被烯上的另一个取代基和适当的外部刺激(如胺)之间的超分子相互作用所超越。因此,螺旋反转是通过一种新颖的轴向-螺旋交流机制实现的,为驯服手性动态螺旋聚合物的螺旋打开了一个新局面。
