“…Compound 2 showed a weaker emission peak centered at 437 nm as excited at 376 nm. Compared with the emission of free ligand H 3 L, the similar emission shapes and the minor shifts in wavelength suggest that the emissions of compounds 1 and 2 may be mostly due to metal-perturbed intraligand emissions as seen in the reported coordination compounds of Zn 2+ or Cd 2+ . , …”

Two interesting homochiral coordination polymers based on in situ produced zinc(II)/cadmium(II) clusters, namely, {[Zn4(L)2(OH)2(H2O)3]·3H2O} n (1) and {[Cd3(L)2(H2O)4]·4H2O} n (2), were hydro/solvothermally synthesized by the reaction of the designed enantiomerically pure chiral ligand (S)-5-((2-carboxy-5-oxopyrrolidin-1-yl)methyl)isophthalic acid (H3L) with Zn(OH)2 or Cd(OH)2. Complex 1 is a three-dimensional (3D) metallohelicate constructed from novel six-fold helical chain substructures based on tetranuclear zinc(II) clusters. Complex 2 is a 2D double-layered metallohelicate containing interesting four-fold helical chain substructures based on trinuclear cadmium(II) clusters. Topologically, 1 can be described as an interesting (3,4,7)-connected net with a point symbol of (42·6)(42·64)(44·615·82), while 2 can be reducible to a (3,6)-connected kgd net. Thermal analyses disclosed that the dehydrated frameworks of 1 and 2 had excellent thermostability. Clearly, the in situ produced zinc(II)/cadmium(II) clusters are of great significance not only in the formation of novel helical frameworks of 1 and 2 but also in the excellent thermostability of their frameworks. Furthermore, their solid-state optical properties, including CD spectra and nonlinear optical and luminescence properties, were also carried out. In particular, 1 and 2 show remarkable second harmonic generation with efficiencies about 1.15 and 0.95 times that of potassium dihydrogen phosphate, respectively. Even more important, the high thermostability and remarkable second harmonic generation response of colorless transparent crystalline materials 1 and 2 are meaningful for further exploring their optical applications.

Chiral metal‐organic framework (CMOFs) is a kind of material with great application value in recent years. Formed by the coordination of metal ions or metal clusters with organic ligands. It is widely used in chemistry, biology, medicine and materials science because of its ordered and adjustable pores, multi‐dimensional network structure, large specific surface area and excellent adsorption properties. In this paper, the synthesis strategies and preparation methods of chiral metal‐organic frameworks are reviewed. In addition, the applications of chiral metal‐organic framework materials in enantiomer recognition and separation, circularly polarized luminescence and asymmetric catalysis are systematically summarized. Finally, the challenges and prospects of the development of chiral metal‐organic frame materials are analyzed in detail.
