Anthracene–phenyl-vinyl–quinoline: a molecular rotor with a large Stokes shift and solvatofluorochromism for lipid-droplet imaging

Year: 2026

Type: article

Abstract: ) and exceptional solvatofluorochromism (156 nm emission shift from hexane to DMSO). Its viscosity-responsive fluorescence due to restricted intramolecular rotation (RIR), as evidenced by fluorescence anisotropy in POPC membranes with varying mol% of cholesterol, has been investigated. Furthermore, it exhibits preferential lipid-droplet imaging and ferroptosis-associated cellular stress. These unique features establish 9-AnPhVQ as a promising molecular rotor probe for fluorescence-based sensing and lipid-droplet imaging.
