    d-电子诱导的基于溴化TTF供体的pi-d相互作用系统的负磁阻。
    摘要:
    基于溴化TTF型的新型pi-d相互作用系统(EDT-TTFBr2)2FeBr4(EDT-TTFBr2 = 4,5-二溴-4',5'-乙撑二硫代四硫富瓦烯)及其非磁性阴离子类似物(EDT-TTFBr2)2GaBr4对有机供体进行了研究。准1Dπ电子系统的盐是金属的,其中金属绝缘子跃迁分别发生在FeBr4-和GaBr4-盐的约20和70 K处,其中低温绝缘状态与电荷有序或莫特绝缘子,然后在较低温度下进行反铁磁转变。FeBr4-盐的特征是在Neel温度(TN)= 11 K时阴离子d自旋具有反铁磁跃迁,尽管其与阴离子-阴离子Br-Br的接触时间长,但仍显着较高,这表明pi-d相互作用的重要性在磁性。令人惊讶的强大的pi-d相互作用,约。从磁化曲线估计的-22.3 K证明了供体分子被溴取代的化学修饰对实现强分子间相互作用的有用性。阴离子d自旋的反铁磁态通过强pi-d相互作用影响导电pi电子的传输,这

  • Efficient synthesis of brominated tetrathiafulvalene (TTF) derivatives: solid-state structure and electrochemical behaviour
    作者:Antonio Alberola、Rebecca J. Collis、Felipe García、Ruth E. Howard

    日期:2006.8
    An efficient synthesis is reported for 4,5-dibromo-[1,3]dithiole-2-thione (1) and 4-bromo-1,3-dithiole-2-thione (7) by bromination of lithiated vinylene trithiocarbonate. Compound 1 acts as a convenient precursor to a number of asymmetric electron donors. This is exemplified by the formation of 4,5-dibromo-4′,5′-bis(2′-cyanoethylsulfanyl)TTF (3) by cross-coupling methodology and subsequent conversion

    The halogenated tetrathiafulvalenes, Br2-EDT-TTF and I2-EDT-TTF were prepared by the coupling route from the corresponding 4,5-dibromo- or 4,5-diiodo-1,3-dithiole-2-thione. In the isostructural series, (Br2-EDT-TTF)2IBr2, (Br2-EDT-TTF)2I3 and (I2-EDT-TTF)2I3, noted Br2/IBr2, Br2/I3 and I2/I3 respectively, short (3.42–3.60 Å) and directional Hal⋯Hal interactions are identified between donor molecules and with the anions, stabilising rare β′ phases. These interactions play not only a structural role but also contribute to the electronic dispersion thanks to sizeable coefficients on the halogen atoms in the HOMOs of Br2-EDT-TTF and I2-EDT-TTF. The three salts behave as Mott insulators as reflected by a high room temperature conductivity (0.5 S cm−1) with an activation energy which increases in the order Br2/IBr2 (730 K), Br2/I3 (1260 K), I2/I3 (1330 K) and a weak magnetic susceptibility, which decreases abruptly below 150 K with no sign of an antiferromagnetic ground state.
    卤化的四硫富瓦烯 Br2-EDT-TTF 和 I2-EDT-TTF 通过相应的 4,5-二或 4,5-二-1,3-二硫醇-2-酮的偶联途径制备。在同构系列中,(Br2-EDT-TTF)2IBr2、(Br2-EDT-TTF)2I3 和 (I2-EDT-TTF)2I3,分别记为 Br2/IBr2、Br2/I3 和 I2/I3,鉴定出短程(3.42–3.60 Å)且定向的卤-卤相互作用存在于供体分子与阴离子之间,从而稳定了稀有的 β′ 相。这些相互作用不仅发挥结构作用,还通过 Br2-EDT-TTF 和 I2-EDT-TTF 中 HOMOs 上卤素原子的显著系数对电子分散产生贡献。这三种盐表现出莫特绝缘体特性,其高室温电导率(0.5 S cm⁻¹)反映出其活化能按 Br2/IBr2 (730 K)、Br2/I3 (1260 K) 和 I2/I3 (1330 K) 的顺序增加,且具有较弱的磁化率,在 150 K 以下急剧下降,未出现反磁基态的迹象。

  • Syntheses and Properties of Halogenated EDT-TTF Derivatives
    作者:Ulrich Kux、Hironori Suzuki、Shigeru Sasaki、Masahiko Iyoda
    DOI:10.1246/cl.1995.183
    日期:1995.3
    Chlorination and bromination of EDT-TTF produced mainly the dihalogenated products (EDT-TTFCl2 and EDT-TTFBr2) with small amounts of the monohalogenated derivatives. In contrast, iodination of EDT-TTF afforded the monoiodinated derivative as the major product, together with the diiodinated compound. The molecular structures of EDT-TTFCl2 and EDT-TTFBr2 have been determined, and the conductivities of CT-complexes and radical salts of new donors reported here have been measured.
    EDT-TTF的化与化反应主要生成二卤化产物(EDT-TTFCl2和EDT-TTFBr2),以及少量单卤化衍生物。相比之下,EDT-TTF的化反应则主要生成单化衍生物,以及二化化合物。EDT-TTFCl2和EDT-TTFBr2的分子结构已经确定,本文报道的CT络合物和新型供体自由基盐的导电性也已测定。
