    摘要:
    机械变色发光(ML)是指固态材料在机械扰动诱导下发生的发光颜色和/或强度变化。对于有机分子固体来说,这种现象与单个荧光团的特定堆积模式和取向有关,它们可能会产生不同的激发态相互作用。以前曾发现二氟硼二苯甲酰甲烷(BF2dbm)衍生物分子固体在室温下表现出可逆的 ML,有望成为自修复光学材料。在本报告中,我们试图了解固态 BF2dbm 分子之间的激发态相互作用,并阐明这些相互作用在机械刺激下是如何变化的,从而揭示 BF2dbm ML 的机理。我们首先研究了单体、二聚体和聚合 BF2dbm 衍生物在光学稀释溶液中的光学特性,并明确证明 BF2dbm 分子有形成 H-聚集体的倾向。接下来,我们研究了这些硼复合物在固态下的物理性质,包括它们的晶体结构、荧光发射和机械变色发光。通过将溶液数据与固态表征结果相关联,我们得出结论:在固态下观察到的 BF2dbm ML 是由两个耦合过程造成的:力诱导的发射性 H-聚集体的形成和向发射性 H-聚集体的能量转移。

  • Substituent-dependent backward reaction in mechanofluorochromism of dibenzoylmethanatoboron difluoride derivatives
    作者:Takehiro Sagawa、Fuyuki Ito、Atsushi Sakai、Yudai Ogata、Keiji Tanaka、Hiroshi Ikeda

    of activation (ΔH‡) of BF2DBM derivatives with MeO groups (2aBF2) was larger than that of derivatives with alkyl groups (2b-dBF2), whereas the entropy of activation (ΔS‡) was smaller than that of the derivatives with alkyl groups. It is proposed that the reaction dynamics of 2aBF2 will be governed by rotational motion around the C(methyl)–O bond. Interestingly, the Gibbs energies of activation (ΔG‡)
    基于动力学和热力学定量评估了二苯甲酰甲基氨基硼酸二氟化物(BF 2 DBM)衍生物的机械氟致变色反应所伴随的热后向反应。通过评估温度对通过机械研磨获得的无定形样品的荧光强度随时间的变化的影响,讨论了动力学。基于差示扫描量热法获得的非晶-晶体相变数据,讨论了热力学。具有MeO基团(2a BF 2)的BF 2 DBM衍生物的活化焓(ΔH ‡))大于具有烷基的衍生物(2b - dBF 2),而活化熵(ΔS ‡)小于具有烷基的衍生物。有人提出2a BF 2的反应动力学将由围绕C(甲基)-O键的旋转运动控制。有趣的是,尽管ΔH ‡和ΔS ‡很大程度上取决于取代基的身份,但BF 2 DBM系列所有成员的反应的吉布斯活化能(ΔG ‡)是可比的。提出取代基依赖性的ΔS ‡项是理解与非晶-晶体相变有关的BF 2 DBM衍生物的机械氟致变色作用的关键参数之一。这些发现还将提供对从熔融状态转变为结晶状态的晶核形成过程的重要见解。

    series of boron ketoiminate derivatives that exhibited clear aggregation‐induced emission (AIE) characteristics (in THF: ΦPL≤0.01; in the solid state: ΦPL=0.30–0.76) were prepared by the reactions of 1,3‐enaminoketone derivatives with boron trifluoride–diethyl etherate. The structures and optical properties were investigated by UV‐visible spectroscopy, photoluminescent (PL) spectroscopy, and X‐ray

  • Crystal structures and excimer fluorescence of anisoylbenzoylmethanatoboron and dianisoylmethanatoboron difluorides

    The crystal structures and spectral-luminescence properties of anisoylbenzoylmethanatoboron difluoride (1) and dianisoylmethanatoboron difluoride (2) were studied in the solid state and in solution. The structural features of Compounds 1 and 2 are responsible for the Occurrence of a new type of excimers in Solutions, which differs from that observed in the crystalline state.
  • Dicyanoboron diketonate dyes: Synthesis, photophysical properties and bioimaging
    作者:Yan Zhou、Yu-Zhe Chen、Jian-Hua Cao、Qing-Zheng Yang、Li-Zhu Wu、Chen-Ho Tung、Da-Yong Wu
    DOI:10.1016/j.dyepig.2014.07.001
    日期:2015.1
    A new class of dicyanoboron diketonates (B(CN)(2)) was synthesized and the photophysical properties were investigated. The B(CN)(2) complexes exhibited high molar absorption coefficients, large Stokes shifts, high photostability and low cytotoxicity. Especially, the emission of the B(CN)(2) extended into the deep red region. The extensive it conjugation and the presence of intramolecular charge transfer (ICT) transitions are responsible for their red-shifted emission. Their fluorescence are very sensitive to the polarity of the solvents. They are highly emissive in low polarity solvents, but weakly fluorescent in polar solvents. Cell imaging experiments demonstrated its potential application as a probe in bioorganisms due to its excellent imaging contrast. This strategy represents a facile approach to modulate the photophysical properties of dyes. (C) 2014 Elsevier Ltd. All rights reserved.
