Dual-mode multi-color circularly polarized luminescent MOFs from a facile approach of chiral induction

Abstract

Metal-organic frameworks (MOFs) have attracted exclusive attention for several practical applications. However, rapid and handy preparation of functional MOFs with circularly polarized luminescence (CPL) has rarely been reported. In this...

Chiral hybrid manganese(ii) halide clusters with circularly polarized luminescence for X-ray imaging

“…Materials with circularly polarized luminescence (CPL) have attracted widespread attention due to their wide potential applications for 3D displays, optical data storage, photoelectric devices, asymmetric synthesis, and so on. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] In general, the degree of circular polarization is defined by the strength of left and right circularly polarized light (I L and I R ). 20 In order to effectively evaluate the intrinsic properties of CPL materials, the luminescence dissymmetry factor (g lum ) is defined as the difference between the strength of I L and I R divided by their average total luminescence strength, namely g lum = 2 Â (I L À I R )/ (I L + I R ).…”

Internal Electric Field‐Modulated Charge Migration Behavior in MoS2/MIL‐53(Fe) S‐Scheme Heterojunction for Boosting Visible‐Light‐Driven Photocatalytic Chlorinated Antibiotics Degradation

“…[ 21,23 ] Previous literatures have reported that more S‐edge active sites are obtained in the small‐size MoS 2 (S‐MoS 2 ) nanoparticular and the electron migration capability is enhanced as well. [ 24 ] However, rapid photo‐generated electron‐hole pair recombination rate limits its further application. Therefore, various materials as electron acceptor have been applied to modify MoS 2 for suppressing photo‐generated electron‐hole pair recombination.…”

Spontaneous resolution of two chiral metal–organic frameworks through local geometric and lattice frustration effects

“…Without the intervention of preexisting homochiral building blocks-as is prevalent within Nature-chiral induction within synthetic materials remains a challenging yet important goal for achieving several applications that require non-centrosymmetry. These include nonlinear optics, 1 enantioselective synthesis, 2 and circularly polarised luminescence, 3,4 among others. 5,6 Metal-organic frameworks (MOFs) are a promising class of materials with which to achieve chiral induction due to their inherent structural and chemical modularity.…”
