Wang, Tao Wu, Ziye Sun, Wei Jin, Shengye Zhang, Xingyuan Zhou, Chuanyao Jiang, Jun Luo, Yi Zhang, Guoqing Macroscopic Wires from Fluorophore-Quencher Dyads with Long-Lived Blue Emission We report the formation of macroscopic wires up to centimeters in length from a series of structurally flexible, covalently tethered small-molecular fluorophore-quencher dyads (FQDs, average MW = 425 Da), comprised of carbazole, melatonin, and cyanobenzoate moieties. These FQDs are nonemissive in organic solutions but become moderately to highly luminescent (Φ<sub>F</sub> = 0.037–0.39) upon formation of wires with emission maxima in the blue region (446–483 nm). The blue photoluminescence (PL) is ascribed to a combination of singlet charge transfer, localized triplet state, and possibly delayed fluorescence emissions with intrinsic luminescence lifetimes ranging from 0.228 to 21333 μs, based on luminescence, transient absorption measurements, X-ray diffraction, and calculations. luminescence lifetimes;calculation;series;21333 μ;FQD;cyanobenzoate moieties;melatonin;Fluorophore-Quencher Dyads;macroscopic wires;singlet charge transfer;nm;carbazole;triplet state;Da;photoluminescence;PL;emission maxima;combination;MW;formation;absorption measurements;X-ray diffraction;Macroscopic Wires;0.228;small-molecular fluorophore-quencher dyads;nonemissive;region;solution;Long-Lived Blue Emission;length;fluorescence emissions;covalently 2017-08-30
