Assembly of pinwheel/twist-shaped chiral lanthanide clusters with rotor structures by an annular/linear growth mechanism and their magnetic properties

Abstract

Although progress has been made in the design and synthesis of chiral lanthanide clusters with pleasing structural connections and special shapes, assembly rules that guide their directional construction are still...

Coordination recognition of differential template units of lanthanide chiral chain

“…12–16 Coordination-driven self-assembly can simulate the self-recognition process among chiral template units of different configurations, providing new research ideas for simplifying and simulating the formation of complex chiral macromolecules having multilevel structures from simple primitives in living organisms. 17–20 In addition, chiral lanthanide complexes show attractive application prospects in the fields of enantioresolution, molecular recognition, nonlinear optics and asymmetric catalysis. In 2017, Cui et al reported a chiral porous octahedral cage that can serve as an efficient asymmetric supramolecular catalyst to achieve high catalytic activity and selectivity.…”

“…30,31 In 2022, we performed for the first time the directional construction of two chiral lanthanide clusters having different nucleus numbers by manipulating the ring growth mechanism and subsequently proposed a linear growth mechanism to construct linear hexanuclear chiral lanthanide clusters. 18,19 To date, it is unknown whether chiral template primitives have considerable recognition ability for specific configurations during the self-assembly process. The selective recognition ability for specific configurations is crucial in analyzing chirality in living organisms and building an effective platform for research on simplifying the connection of chiral units to form complex chiral compounds.…”

Different anion (NO3− and OAc−)-controlled construction of dysprosium clusters with different shapes

“…5 Based on the use of the MCC method, we proposed multiple growth mechanisms (i.e., out-to-in, planar epitaxial/internal, linear and annular growth mechanisms) to guide the formation of lanthanide clusters. [53][54][55][56] In the synthesis process of lanthanide clusters, main factors that are often considered, to be regulated, include the coordination sites of organic ligands, coordination anions, temperature and reaction solvents. [50][51][52][53] In 2019, our research group successfully constructed two butterfly-shaped Ni III 2 Dy III 2 clusters by adjusting substituents (-H and -CH 3 ) with multidentate chelating ligands.…”

Highly stable and differentially arranged hexanuclear lanthanide clusters: structure, assembly mechanism, and magnetic resonance imaging

“…We also proposed the out-to-in, linear, and annular growth mechanisms to guide the directional synthesis of lanthanide clusters. [24][25][26][27][28] In 2020, our research group successfully constructed a double-cage dysprosium cluster Dy 60 using a multidentate chelating coordination method, tracked the Dy 60 formation process using HRESI-MS, and proposed the possible self-assembly mechanism of Dy 60 . 29 In 2021, we first proposed that the out-to-in growth mechanism guides the directional construction of 16 nuclear discotic lanthanide clusters.…”
