Chemical Society Reviews, Journal Year: 2024, Volume and Issue: 53(13), P. 6694 - 6734

Published: Jan. 1, 2024

Delayed luminescence (DF), including phosphorescence and thermally activated delayed fluorescence (TADF), circularly polarized (CPL) exhibit common broad application prospects in optoelectronic displays, biological imaging, encryption. Thus, the combination of is attracting increasing attention. The encapsulation guest emitters various host matrices to form host-guest systems has been demonstrated be an appealing strategy further enhance and/or modulate their luminescence. Compared with conventional liquid crystals, polymers, supramolecular matrices, porous crystalline frameworks (PCFs) metal-organic (MOFs), covalent-organic (COFs), zeolites hydrogen-bonded organic (HOFs) can not only overcome shortcomings such as flexibility disorder but also achieve ordered guests long-term stability chiral structures, providing new promising platforms for development DF CPL. In this review, we provide a comprehensive critical summary recent progress photochemistry

Stereocontrolled Self-Assembly of a Helicate-Bridged Cu^I₁₂L₄ Cage That Emits Circularly Polarized Light

Journal of the American Chemical Society, Journal Year: 2024, Volume and Issue: 146(4), P. 2379 - 2386

Published: Jan. 22, 2024

Control over the stereochemistry of metal–organic cages can give rise to useful functions that are entwined with chirality, such as stereoselective guest binding and chiroptical applications. Here, we report a chiral CuI12L4 pseudo-octahedral cage self-assembled from condensation triaminotriptycene, aminoquinaldine, diformylpyridine subcomponents around CuI templates. The corners this consist six head-to-tail dicopper(I) helicates whose helical chirality be controlled by addition enantiopure 1,1′-bi-2-naphthol (BINOL) during assembly process. Chiroptical nuclear magnetic resonance (NMR) studies elucidated process mechanism stereochemical information transfer BINOL Initially formed CuI(BINOL)2 thus underwent ligand exchange formation helicate cage, which determined overall stereochemistry. resulting were also shown generate circularly polarized luminescence.

Covalent Post‐Synthetic Modification of Metal‐Organic Cages: Concepts and Recent Progress

Chemistry - A European Journal, Journal Year: 2024, Volume and Issue: 30(24)

Published: Jan. 31, 2024

Abstract Metal‐organic cages (MOCs) are supramolecular coordination complexes that have internal cavities for hosting guest molecules and exhibiting various properties. However, the functions of MOCs limited by choice building blocks. Post‐synthetic modification (PSM) is a technique can introduce new functional groups replace existing ones on without changing their geometry. Among many PSM methods, covalent promising approach to modify with tailored structures functions. Covalent be applied either cavity or external surface MOCs, depending functionality expected customized. there still some challenges limitations in field such as balance between stability harshness organic reactions involved PSMs. This concept article introduces reaction types applications after modification, summarizes provides an outlook this research field.
