A review on chiral metal–organic frameworks: synthesis and asymmetric applications

Abstract

Chiral metal organic frameworks (CMOFs) have the characteristics of framework structure diversity and functional tunability, and have important applications in the fields of chiral identification, separation of enantiomers and asymmetric...

Enantioseparation Membranes: Research Status, Challenges, and Trends

“…MOF materials with periodic network structures are self‐assembled by metal nodes and organic ligands. [ 55–58 ] MOF with porous structure and large specific surfaces have great development potential in the field of separation. [ 59–62 ]…”

“…MOF materials with periodic network structures are self-assembled by metal nodes and organic ligands. [55][56][57][58] MOF with porous structure and large specific surfaces have great development potential in the field of separation. [59][60][61][62] Jin's group [63] used a chiral MOF for the first time in the preparation of enantioseparation membranes.…”

Chiral metal–organic frameworks for photonics

“…Chiral MOFs have seen extensive use in a range of applications such as chiral separations, enantioselective catalysis, and chiral sensing; all of which have been the subject of recent reviews. 2,[8][9][10][11][12] These processes all involve a physical interaction between the chiral framework and a guest or analyte. In contrast, the interaction of light with chiral MOFs gives rise to interesting optical and photonics applications, which are relatively less explored in the literature.…”

“…In particular, MOFs exhibiting circularly polarised luminescence (CPL) and chiroptical switching are in their infancy and have only received brief coverage in recent reviews. 10,11 Therefore, we aim to provide a more thorough examination of how chiral MOFs have been used for these applications and the enormous potential for future growth in this direction. Chiral MOFs are inherently noncentrosymmetric, meaning they are also candidate materials for second-order nonlinear optics (NLO).…”

The development of chiral metal–organic frameworks for enantioseparation of racemates

“…[30][31][32][33][34][35][36] Various CMOFs are synthesized by PSM of achiral MOFs. [37][38][39][40][41][42][43] Such as CMOF which is difficult to obtain by the simple solvothermal postsynthetic method, it is prepared alternatively by the introduction of two chiral saline moieties in UiO-68. 44 Similarly, a very facile and economically favourable method is introduced for the Zr-based MOFs by the replacement of coordinated molecules with zirconium metal in MOF-808.…”
