  • High Performance White Organic Light-Emitting Diodes with Blue Fluorescence and Red Phosphorescence

    日期:2017.8.1
    Highly efficient blue emitting material (DAnP) consisting of anthracene and pyrene was designed and synthesized. The PLmax of the DAnP is 469 nm in the solution state and 480 nm in the film state. DAnP was used as non-doped emitting layer (EMLs) in OLEDs with the following structures: ITO/2-TNATA (60 nm)/NPB (15 nm)/DAnP (35 nm)/Alq3 (20 nm)/LiF (1 nm)/Al (200 nm). The DAnP device has current efficiency of 5.45 cd/A, power efficiency of 2.71 lm/W, and CIEs of (0.19, 0.40) at 10 mA/cm2. An efficient multilayer white organic light-emitting diode (WOLED) with the structure of ITO/NPB (30 nm)/CBP: 3 wt% Ir(piq)3 (10 nm)/DAnP (40 nm)/TPBi (40 nm)/LiF (1 nm)/Al (200 nm) was fabricated and characterized, where DAnP and tris(1-phenylisoquinoline) iridium (III) [Ir(piq)3] were used as a blue fluorescent emitter and a red phosphorescent emitter respectively. A WOLED showed current efficiency of 5.08 cd/A, power efficiency of 2.55 lm/W, and CIEs of (0.35, 0.36) at 10 mA/cm2.

  • Solvatochromic Pyrene Analogues of Prodan Exhibiting Extremely High Fluorescence Quantum Yields in Apolar and Polar Solvents
    作者:Yosuke Niko、Susumu Kawauchi、Gen-ichi Konishi
    DOI:10.1002/chem.201301020
    日期:2013.7.22
    True colors: Novel pyrene analogues of Prodan exhibit outstanding photophysical properties with remarkably high fluorescence quantum yield (QY) in solvents ranging from apolar hexane to polar methanol (see figure). This is accompanied by strong solvatochromism and large Stokes shifts. These properties have not been previously achieved in enormous solvatochromic dyes, but are quite useful for emitting

  • Fluorescence Enhancement of Pyrene Chromophores Induced by Alkyl Groups through σ–π Conjugation: Systematic Synthesis of Primary, Secondary, and Tertiary Alkylated Pyrenes at the 1, 3, 6, and 8 Positions and Their Photophysical Properties
    作者:Yosuke Niko、Susumu Kawauchi、Shun Otsu、Katsumi Tokumaru、Gen-ichi Konishi
    DOI:10.1021/jo400128c
    日期:2013.4.5
    We have systematically synthesized 1-, 3-, 6-, and 8-alkyl-substituted pyrene derivatives using the latest synthesis methods and investigated the effects of alkyl substitution on the photophysical properties of the pyrene chromophore. Like the trimethylsilyl group, which is known to enhance the fluorescence properties of some chromophores through sigma*-pi* conjugation, alkyl groups (primary, secondary, and tertiary) enhanced the fluorescence quantum yield of the pyrene chromophore through sigma-pi conjugation in most cases. While these enhancements in the fluorescence quantum yield were beyond expectations, the results were supported by absolute measurements. These results also indicate that ubiquitous alkyl groups can be used to tune the photophysical properties of the pyrene chromophore, as well as to improve the solubility or prevent aggregation. In other words, they can be used to develop new photofunctional materials.
  • Synthesis of unsymmetrically substituted pyrene derivatives through (6-bromo-3,8-dibutylpyren-1-yl)trimethylsilane

    A straightforward route to unsymmetrically functionalized pyrene derivatives is described involving the synthesis of key precursor (6-bromo-3,8-dibutylpyren-1-yl)trimethylsilane 1. In a first step bromide 1 was successful in Suzuki–Miyaura, Sonogashira, and Buchwald–Hartwig cross-coupling reactions. Subsequent transformation of the trimethylsilyl group to bromide enabled the introduction of a second

    dependence of the properties of the compounds on the position of substitution of the pyridyl moieties connecting to the pyrene core. It was found that the absorption spectra of 2- and 4-substituted pyrene derivatives display similar and weak influence on the S2 ← S0 excitations, whereas they are quite different from those of 1-substituted isomers. The emission spectra of 1- and 4-substituted pyrenes are
    为了研究of核心上吡啶基取代基的“位点效应”,合成并表征了四个区域异构的单吡啶基-py(1-4)和五个区域异构的二吡啶基-((5-9)共轭物,并通过单晶X证实了其结构射线衍射。已通过实验和理论研究了这些化合物的光物理性质和相关的前沿轨道特征,并证明了这些化合物的性质对与to核连接的吡啶基部分的取代位置的依赖性。发现2-和4-取代的derivatives衍生物的吸收光谱对S2←S0激发表现出相似而微弱的影响,而它们与1-取代的异构体却有很大不同。1-和4-取代的pyr的发射光谱非常相似,而2-取代的异构体的发射光谱显示最大的红移。1,6-二取代的化合物5在溶液中具有近统一的发射量子产率,几乎是其他区域异构二吡啶基-吡啶的三倍。此外,在本研究制备的所有10个吡啶基-吡啶中,四取代的1,6-二吡啶基-3,8-二正丁基-butyl(10)表现出最高的固态量子产率0.24。
