  • Alcohol Dimer is Requisite to Form an Alkyl Oxonium Ion in the Proton Transfer of a Strong (Photo)Acid to Alcohol
    作者:Sun-Young Park、Young Min Lee、Kijeong Kwac、Yousung Jung、Oh-Hoon Kwon
    DOI:10.1002/chem.201503948
    日期:2016.3.18
    basic behavior by donating or accepting a proton. In this study, proton dissociation of a model photoacid in solution is explored by using time‐resolved spectroscopy, revealing quantitatively for the first time that alcohol acts as a Brønsted base because of H‐bonded cluster formation to enhance the reactivity. The protonated alcohol cluster, the alkyl oxonium ion, can be regarded as a key reaction intermediate
    醇是最简单的两性有机化合物,通过捐赠或接受质子,可以表现出酸性或碱性行为。在这项研究中,使用时间分辨光谱法研究了溶液中模型光酸的质子解离,首次定量地揭示了由于H键团簇形成以增强反应性,醇作为布朗斯台德碱。质子化的醇簇,烷基氧鎓离子,可以被认为是成熟的醇脱水反应中的关键反应中间体。与在水中一样,该发现表明质子溶剂分子在促进非水酸碱反应中具有协同作用。
  • <scp>Acid–base</scp> reaction of a <scp>super‐photoacid</scp> with a cooperative amide <scp>hydrogen‐bonded</scp> chain

    one for NMB indicating that the ESPT of NM7HQ+ occurs with the H-bonded chain of two NMB molecules. Our study highlights the cooperative nature of H-bonding in the chemical reactivity of amide in acid–base reactions as has already been reported for alcohol.
    在N-甲基苯甲酰胺 (NMB) 作为碱存在于非质子极性溶剂乙腈中的情况下,研究了强光酸N-甲基-7-羟基喹啉 (NM7HQ + )的激发态质子转移 (ESPT)。根据 Benesi-Hildebrand 关系,NM7HQ +和 NMB 的氢 (H) 键络合物以 1:1 的化学计量比以基态存在,缔合常数为 22.2 ± 1.7 M -1。观察到 1:1 复合物的荧光猝灭遵循 Stern-Volmer 关系,其中 NMB 的分子数表明 NM7HQ +的 ESPT发生在两个 NMB 分子的 H 键链上。我们的研究强调了在酸碱反应中酰胺的化学反应性中氢键的协同性质,正如已经报道的醇。
  • Excited-state proton-transfer dynamics of 1-methyl-6-hydroxyquinolinium embedded in a solid matrix of poly(2-hydroxyethyl methacrylate)
    作者:Sun-Young Park、Young-Shin Lee、Du-Jeon Jang
    DOI:10.1039/b811180d
    日期:——
    The excited-state intrinsic proton transfer and its geminate recombination, as well as the ground-state equilibria, of 1-methyl-6-hydroxyquinolinium embedded in a solid matrix of poly(2-hydroxyethyl methacrylate) have been studied by measuring time-resolved and steady-state fluorescence spectra along with absorption and excitation spectra. Proton transfer takes place within 3.3 ns to form ion pairs while its back-reaction occurs on the time scale of 3.7 ns. The ion pairs in the rigid alcoholic matrix go through neither diffusion to form free ions nor subsequent electronic rearrangement to form the keto species within their excited-state lifetimes.
    通过测量时间分辨和稳态荧光光谱以及吸收和激发光谱,研究了嵌入聚(2-羟乙基甲基丙烯酸酯)固体基质中的 1-甲基-6-羟基喹啉的激发态本征质子转移及其基态重组,以及基态平衡。质子转移在 3.3 毫微秒内形成离子对,其反向反应在 3.7 毫微秒内发生。刚性酒精基质中的离子对既没有经过扩散形成自由离子,也没有经过随后的电子重排在其激发态生命周期内形成酮体。
  • Residence and diffusion of a dynamically prototropic hydration probe in AOT reverse micelles
    作者:Aniruddha Adhikari、Jae-Heon Park、Hak-Won Nho、Oh-Hoon Kwon
    DOI:10.1016/j.molliq.2020.114346
    日期:2020.12
    We investigated the hydration dynamics in the nanosized water pool of an Aerosol-OT (AOT) reverse micelle (RM) using a prototropic (proton-donating) fluorescent dye, N-methyl-7-hydroxyquinolinium (NM7HQ+), as the probe. NM7HQ+ is a photoacid, and the deprotonation of its excited-state cationic form (C*) gives rise to a neutral keto species (K*). In the present study, the residence sites of C* and K*
    我们研究了质子传递给质子的荧光染料N-甲基-7-羟基喹啉(NM7HQ +)作为探针在气溶胶-OT(AOT)反胶束(RM)的纳米级水池中的水合动力学。NM7HQ +是一种光酸,其激发态阳离子形式(C *)的去质子化反应生成中性的酮类(K *)。在本研究中,通过监测其时间分辨的荧光各向异性来确定C *和K *在各种大小的水池中的驻留位点。此外,通过将光谱拟合为两个对数正态峰函数的和,分析了时间分辨荧光光谱中C *和K *谱带的演化。具有不同形式电荷的物质的随时间变化的光谱位移揭示了阴离子AOT头基与结合水区域的界面处的特征水合作用,以及探针在RM中的旋转和平移扩散。
