“…In other words, both the molecular-level and microscale chirality contribute to the high g lum . The assembly-and aggregate-induced CPL of metal clusters is also found in gold clusters of Au 3 [R/S-BINAP] 3 Cl and copper clusters of [Cu 14 (R/S-DPM) 8 ] 6+ (DPM = R/S-2-diphenyl-2hydroxylmethylpyrrolidine-1-propyne), which are CPL inactive when dispersed in good solvents (e.g., CH 2 Cl 2 ) but become CPL active in the aggregate states after the addition of poor solvents (e.g., n-hexane) [58,59] .…”

Circularly polarized luminescence (CPL) is an interesting phenomenon representing the unequal emission of left-handed and right-handed polarized light from an emitter. CPL is promising in chirality characterizations and various optical applications. Traditionally, research on CPL is centered on organic substances. In recent years, CPL present on inorganic ones has also become a nascent topic, which is significant to explore novel chirality- and luminescence-related properties and applications in inorganic materials. This minireview summarizes the recent progress on the following two aspects: 1) how to endow common inorganic luminophores with CPL activity; 2) how to use emerging chiral inorganic nanomaterials to design CPL-active systems. The general synthesis strategies, optical properties, applications and outlook of CPL-active inorganic materials are demonstrated.

Within the framework of density functional theory, electronic structures of Linde‐type A (LTA) zeolite membranes are calculated, and based on the electronic structures, several key optical properties of LTA zeolite membranes can be conveniently determined, with the method of the full‐potential linearized augmented plane wave under the random phase approximation for the boundaries and the generalized gradient approximation for the exchange‐correlation potentials. The calculated optical properties as a function of frequency include the real and imaginary parts of the dielectric function ε(ω), the refraction index n(ω), the extinction coefficient κ(ω), the reflectivity R(ω), the energy loss function L(ω), the absorption coefficient α(ω), and finally the optical conductivity σ(ω), along with specific directions of the primitive cell. It is demonstrated that the optical properties of the Sodium LTA zeolite cluster appear anisotropic within the range of ultraviolet. The nature of anisotropy implies that all the functions are 3×3 tensors with non‐zero off‐diagonal elements. Three diagonal and three off‐diagonal elements are simultaneously presented.This article is protected by copyright. All rights reserved.

“…Metal–organic framework (MOF) membranes are formed through the coordination reaction between metal ions and organic ligands, which have attracted the attention of researchers to explore their applications in the fields of separation (e.g., ion separation − and molecular separation − ), detection (e.g., ion detection, , inorganic radioactive gas molecule, , and organic harmful gas molecule detection − ), anticorrosion, , energy capture and conversion (e.g., salinity gradient power generation , and battery , ), and so on because of their large specific surface area, controllable subnanoscale pores, and diverse functional sites. However, MOF materials are not inclined to form large-area crack-free membranes due to the particle form and intrinsic brittleness.…”

Metal–organic framework (MOF) membranes have significant application prospects in different fields, such as separation, detection, anticorrosion and energy capture and conversion and so on. However, the difficulty of constructing free-standing MOF membranes has hindered their applications. Here, we propose a facile strategy to fabricate free-standing MOF sheets with easy-peeling and easy-transfer properties through electrochemical printing on superhydrophobic micropillar-structured substrates. During the electrochemical printing process, electrophoretic deposition will occur along the solid/liquid/gas triphase interface on these substrates. First, the effects of the electrophoretic deposition conditions, such as deposition time and current, on the thickness-controlled growth on superhydrophobic substrates are explored. Then, the influences of the geometric parameters, such as diameter and distance, and wettability of the micropillars on constructing free-standing MOF sheets are systematically studied. Furthermore, the MOF sheets exhibit the properties of capillarity-assisted peeling from superhydrophobic substrates and spreading-assisted transfer to superhydrophilic substrates, followed by the demonstration of the generality. Therefore, it is a facile method to prepare free-standing MOF sheets with easy-peeling and easy-transfer properties taking advantage of electrochemical printing on superhydrophobic substrates, giving impetus to the improvement of the productivity and the corresponding applications in various fields.
