    A series of new metal-free organic dyes based on 3,3′-dithioalkyl-2,2′-bithiophene (SBT) organic chromophores was synthesized for use in dye-sensitized solar cells (DSSCs). Because S(alkyl)⋯S(thiophene) intermolecular interlocking renders the twist angle in the structure as <1°, the SBT core is almost flat, as evidenced by the single crystal, optical, and electrochemical data. Through structural modification
    合成了一系列基于3,3'-二硫代烷基-2,2'-联噻吩(SBT)有机生色团的新型无金属有机染料,用于染料敏化太阳能电池(DSSC)。由于S(烷基)⋯S(噻吩)的分子间互锁使结构中的扭曲角小于1°,因此SBT核几乎是平坦的,如单晶,光学和电化学数据所示。通过对具有不同烷基链和共轭噻吩单元的SBTπ-接头进行结构修饰,可以抑制显着的生色团聚集和界面电荷重组。在所有合成染料中,优化的染料(消光系数高,为1.3×10 4 cm -1 M -1在497 nm波长下)和共吸附的鹅去氧胆酸(CDCA)在1个阳光下(AM 1.5 G,100 mW cm -2)达到了9.46%的功率转换效率(η)。在1个阳光下进行1000小时的测试后,用这种染料和共吸附剂CDCA制成的太阳能电池仍保持其初始效率的88%,而用N719染料制成的电池为69%。此外,当在2400勒克斯的T5荧光灯下测试时,该染料与CDCA的η为12

    The acidityenhancing effect of BH3 in gas‐phase phosphineboranes compared to the corresponding free phosphines is enormous, between 13 and 18 orders of magnitude in terms of ionization constants. Thus, the enhancement of the acidity of protic acids by Lewis acids usually observed in solution is also observed in the gas phase. For example, the gas‐phase acidities (GA) of MePH2 and MePH2⋅BH3 differ
    酸度提高效果BH的3在气相膦⋅硼烷相比于相应的游离的膦是巨大的,大小为13级18之间的订单在电离常数的条款。因此,在气相中也观察到通常在溶液中观察到的路易斯酸对质子酸酸度的增强。例如,麦菲的气相酸度(GA)2和麦菲2 ⋅ BH 3由约118千焦摩尔不同-1(见图)。
  • Detection and kinetic characterization of S<sub>N</sub>V intermediates. Reactions of thiomethoxybenzylidene Meldrum's acid with thiolate ions, alkoxide ions, OH<sup>-</sup>, and water in aqueous DMSO

    日期:1999.6.1
    The reaction of thiomethoxybenzylidene Meldrum's acid (5-SMe) with thiolate and alkoxide ion nucleophiles is shown to proceed by the two-step addition-elimination SNV mechanism in which the tetrahedral intermediate accumulates to detectable levels. For the reactions with thiolate ions, rate constants for nucleophilic addition (k1RX), its reverse (k-1RX), and for conversion of the intermediate to products
    显示硫代甲氧基亚苄基 Meldrum 酸 (5-SMe) 与硫醇盐和醇盐离子亲核试剂的反应通过两步加成 - 消除 SNV 机制进行,其中四面体中间体积累到可检测水平。对于与硫醇盐离子的反应,确定了亲核加成 (k1RX)、其反向 (k-1RX) 和中间体转化为产物 (k2RX) 的速率常数。与醇盐离子反应,只能得到k1RX和k-1RX;这些反应中的中间体没有产生预期的取代产物,因此无法确定 k2RX 值。与 OH- 和水的反应被认为遵循相同的机制,但各自的中间体保持在稳态水平,并且只有 k1OH 和 k1H2O 对 5-SMe 进行亲核攻击是可测量的。

    The kinetics of the title reactions were determined in 50% DMSO-50% water (v/v) at 20 degrees C; n-BuS-, HOCH2CH2S-, and MeO2CCH2S- were used as thiolate ions. The reactions with the thiolate ions gave rise to two separate kinetic processes. The first refers to rapid, reversible attachment of RS- to the substrate leading to a tetrahedral intermediate (k1RS), k(-1)RS, the second to the conversion of
    标题反应的动力学在 50% DMSO-50% 水 (v/v) 中于 20 摄氏度进行测定;n-BuS-、HOCH2CH2S- 和 MeO2CCH2S- 用作硫醇盐离子。与硫醇盐离子的反应产生两个独立的动力学过程。第一个是指 RS- 与底物的快速、可逆连接,导致四面体中间体 (k1RS),k(-1)RS,第二个是中间体转化为产物 (k2RS)。在大多数情况下,可以确定所有速率常数(k1RS、k(-1)RS 和 k2RS。结合先前研究的结果,详细讨论了活化取代基和离去基团对速率常数和平衡常数的影响与本征速率常数一样,与 OH- 的反应仅允许测定 k1OH 对底物的亲核攻击;

    Complexation of 99, 99m Tc(CO) 3 + organometallic fragment with 2 + 1 chelating systems was studied. HPLC analysis showed that the dithiocarbamate complexes of 99m Tc are stronger than their xanthate, acetylacetonate, and γ-methoxycarbonylmethylacetylacetonate analogs. To block the third vacancy in the technetium coordination sphere, we studied thiols, thioethers, primary and secondary amines, hydroxyl ion, imidazole, phosphines, and isocyanides. As determined by 99m Tc NMR spectroscopy, the mixed-ligand complexes Tc(CO)3(DTC)L (DTC is dithiocarbamate and L is isocyanide, imidazole, and phosphine) are the most stable to the histidine challenge reaction. HPLC analysis showed that, among these 2 + 1 systems, only the DTC-isonitrile system forms a single complex with 99m Tc(CO) 3 + . The minimal dithiocarbamate-isocyanide concentration providing complete binding of 99m Tc(CO) 3 + is 10−4 M.
    研究了 99、99m Tc(CO) 3 + 有机金属片段与 2 + 1 螯合体系的络合。高效液相色谱分析显示,99m Tc 的二硫代氨基甲酸盐络合物比黄原酸盐、乙酰丙酮酸盐和γ-甲氧羰基甲基乙酰丙酮酸盐类似物更强。为了阻止锝配位球中的第三个空位,我们研究了硫醇、硫醚、伯胺和仲胺、羟基离子、咪唑、膦和异氰酸酯。根据 99m Tc NMR 光谱测定,混合配体配合物 Tc(CO)3(DTC)L(DTC 为二硫代氨基甲酸酯,L 为异氰酸酯、咪唑和膦类)对组氨酸挑战反应最稳定。高效液相色谱分析显示,在这些 2 + 1 系统中,只有 DTC- 异腈系统与 99m Tc(CO) 3 + 形成单一复合物。能与 99m Tc(CO) 3 + 完全结合的最小二硫代氨基甲酸-异氰酸酯浓度为 10-4 M。
