Summary: | Coordination-driven self-assembly processes often produce remarkable structures. In particular, self-assembly processes mediated by chiral template units have provided research ideas for analyzing the formation of chiral macromolecules in living organisms. In this study, by regulating the proportion of reaction raw materials in the "one-pot" synthesis of lanthanide complexes, we constructed chiral template units with different coordination orientations. As a result, lanthanide chiral chains connected to different structures were obtained through the self-assembly process of coordination recognition. In particular, driven by coordination, chiral template units with codirectional coordination points (called
cis
configuration) coordinate solely with

template units during the self-assembly process to obtain a one-dimensional (1D) chain

with an "S"-shaped distribution. Moreover, chiral template units with reversed coordination sites (called

configuration) and twisted chiral template units are connected solely to templates with the same configuration to form a 1D chain

are two pairs of enantiomers. The controllable construction of these two differential 1D chains is of great significance for studying coordination recognition at the molecular level. To the best of our knowledge, this is the first study to construct a 1D lanthanide chain through the self-assembly process of coordination recognition. The assembly process of nucleotides to form a hierarchical structure is simulated. This work provides a vivid example of the controllable synthesis of lanthanide complexes with precise structures and offers a new perspective on the formation process of chiral macromolecules that simulates natural processes.
By regulating the proportion of the reaction raw materials in the "one-pot" synthesis process, we obtained a recognition function of the supramolecular self-assembly process to simulate the assembly mode of nucleotides. |
