Chiral Amplification and Regulation: Design and Applications of Circularly Polarized Luminescence‐Active Materials Derived From Macrocyclic Compounds

Aggregate, Год журнала: 2025, Номер unknown

Опубликована: Май 9, 2025

ABSTRACT Chirality is a fundamental property in molecules and biological systems, characterized by asymmetric configurational features. Circularly polarized luminescence (CPL) materials have gained significant attention due to their unique optical activities, with applications 3D displays, chiral sensors, catalysis, more. Chiral transfer amplification typically involve the generation of chirality excited state, facilitated interactions like energy transfer, electron or induction. Supramolecular self‐assembly strategies, particularly macrocyclic compounds, enable linking achiral luminescent units through intermolecular interactions. Macrocyclic hosts—cyclodextrins, calix[ n ]arenes, pillar[ cyclophanes, cucurbit[ ]urils—are especially promising stable structures adjustable cavities for guest encapsulation. These compounds induce photophysical properties host–guest complexation, making them ideal constructing amplification, CPL‐active materials. This review summarizes advancements multicolor CPL materials, sensing, induction, separation, highlighting potential supramolecular material design. The challenges future directions this field are also discussed, aiming guide further research application systems.

Construction of coumarin-appended calix[4]arene-based fluorescence sensor for the detection of carbofuran in cabbage

Analytical Methods, Год журнала: 2024, Номер 16(15), С. 2400 - 2411

Опубликована: Янв. 1, 2024

This study presents a novel approach for the detection of carbofuran (CBF) insecticide by systematically exploring calix[4]arene-derived fluorescence probe, CouC4S, functionalized with two coumarin-labelled cystamine linkages at narrow edge calix[4]arene platform. The proposed method showed "signal - off" effect when CBF binds CouC4S quenching intensity CouC4S. Its limit was as low 5.55 μM according to emission study. working concentration range this ligand observed be up 5-65 μM. could applied on-spot in real samples such cabbage spiking CBFvia situ experiments, which exhibited 8.823 ppm. For further confirmation CouC4S:CBF binding, cyclic voltammetry, differential pulse powder X-ray diffraction, FT-IR spectroscopy, 1H NMR titration, MALDI-TOF and computational investigations were carried out.
