Nonvolatile liquid anthracenes for facile full-colour luminescence tuning at single blue-light excitation

Abstract: Nonvolatile room-temperature luminescent molecular liquids are a new generation of organic soft materials. They possess high stability, versatile optical properties, solvent-free fluid behaviour and can effectively accommodate dopant dye molecules. Here we introduce an approach to optimize anthracene-based liquid materials, focussing on enhanced stability, fluorescence quantum yield, colour tunability and processability, with a view to flexible electronic applications. Enveloping the anthracene core in low-vis… Show more

“…Small angle X ray scattering (SAXS) and X ray diffraction (XRD) analysis of the neat liquid samples show that the average distance between the isolated π conjugated units is, for example, 2.1 nm for 21 (Figure 6e). 9 This is due to the bulky substituents which effectively disturb the anthracene core core (π π) interaction. Such molecular design brings a kind of bonus, photo stability; there is no dimerization and relatively slow photo oxidation, about 10 times slower than that of the bare anthracene unit (speci cally, diphenylanthracene), under 365 nm ltered Xe light irradiation.…”
