螺旋性和手性是生命的基本要素。许多重要的生物聚合物,如DNA和肽具有右手螺旋结构,而这些生物聚合物的构建单元分别是d -核糖和l -氨基酸。为了更好地认识生物聚合物螺旋结构的起源,在无机化学和配位化学中,对具有螺旋结构的金属配合物的设计进行了大量的研究。然而,在超分子水平上控制整个结构的手性和螺旋度是螺旋结构设计和合成的主要挑战之一。在这篇文章中,我们介绍了构建螺旋配位化合物的一般方法,并举例说明了构建块的手性与一维链的螺旋度之间的关系,以及螺旋之间的手性转移。
Helicity and chirality are essential elements of life. Many important biopolymers such as DNA and peptides possess right-handed helical structures, while the building blocks for the constructions of such biopolymers are D-ribose and L-amino acids, respectively. For better realizing the origin of the helicity of biopolymers, a tremendous expansion in research efforts has been devoted to the design of metal complexes exhibiting helical architectures in inorganic and coordination chemistry. However, to control the chirality and helicity of the entire structures at the supramolecular level is one of the major challenges in the design and synthesis of helical structures. In this highlight, we present the general approaches for the construction of helical coordination compounds, together with a few instances illustrating the correlation between the chirality of building blocks and the helicity of 1D chains, as well as the chirality transfer among the helices.
