Herein, by self‐assembling 4,4′,4′′‐nitrilotribenzoic acid (H 3 NBA) with bis(cyclopentadienyl)‐zirconium dichloride (Cp 2 ZrCl , Cp=η 5 ‐C H ) different solvent conditions, we have obtained three hierarchical packing modes metallo‐tetrahedra distinct spatial symmetry groups (designated as Zr‐α, Zr‐β, and Zr‐γ). Among them, Zr‐α employs a simple cubic arrangement common centrosymmetric superstructure, which consists pair equimolar enantiomers its unit cell. While Zr‐β results conglomerates spontaneous resolution without using any resolving agents, giving rise two enantiopure entities separately (Zr‐β‐ P Zr‐β‐ M ).

The development of covalent organic framework (COF) films featuring circular polarization luminescence (CPL) probing remains a formidable challenge. Herein, we developed chiral cross-linked COF film to obtain uniform and dense (chirCOFilm) possessing highly sensitive CPL for enantiomers. axial cross-linkers (R-/S-BBNA) are initially introduced into the channels (COFilm/R-BBNA or COFilm/S-BBNA) by vapor-assisted epitaxial method. Then, olefin groups in R-/S-BBNA layers undergo cross-linking reaction under UV irradiation, forming chirCOFilm. obtained chirCOFilms have strong chirality with mirror images, fluorescence discoloration, intense properties. A multitude rich photopatterns chirCOFilm/PDMS flexible prepared taking advantage photochromic properties during illumination, showing potential application advanced anticounterfeiting. More importantly, realize phenethylamine enantiomers at 5% concentration, which can hardly be achieved from their corresponding probing. This study not only provides new strategy preparing using but also opens avenue achieving though CPL.

Abstract Circularly polarized luminescence (CPL) materials hold significant promise in multidisciplinary fields such as circularly organic light‐emitting diodes, biological probes, data storage, and information encryption. However, these cutting‐edge applications also put forward higher requirements for the design of CPL materials, requiring large dissymmetry factor high emission quality. For this purpose, diverse approaches have been explored to generate enhance emission. Among them, energy transfer (ET) strategy stands out it can be readily implemented a wide range materials. The present work overviews latest advances generating modulating CPL, involving small molecules, polymers, metal complexes, liquid crystals, well new‐emerging chiral luminescent It is anticipated that review article will garner increased attention toward systems facilitate advancement
