π-π and donor–acceptor intermolecular interactions is observed in the solid state architecture of this precursor. Its condensation reaction with 2-ethanolamine provided the chelating electroactive ligand 4-TTF-2-((2-hydroxyethyl)iminomethyl)-phenol 2 (H 2 L 1 ). Reaction with Cu(OAc) 2 in a 2:1 stoichiometry afforded the one-dimensional coordination chain-like polymer [Cu(HL 1 ) 2 ] n 3 for which the
摘要通过TTF-SnMe 3与5-溴-水杨醛之间的斯蒂勒偶联反应制备了TTF-水杨醛1,并通过单晶X射线结构分析对其进行了表征。在该前体的固态结构中观察到一组S⋯S,π-π和供体-受体分子间的相互作用。其与2-乙醇胺的缩合反应提供了螯合的电活性配体4-TTF-2-((2-羟乙基)亚氨基甲基)-苯酚2(H 2 L 1)。与化学计量比为2∶1的Cu(OAc)2反应,得到一维配位链状聚合物[Cu(HL 1)2] n 3,已经确定了其固态结构。Cu(II)配位球在赤道面上包含一个由两个螯合亚氨基苯酚单元产生的N2O2基序,而轴向位置被顶部和底部相邻链内复合物的羟基-乙基侧基悬垂的羟基配体占据,具有较大的Cu-O距离,表明Jahn-Teller伸长。TTF单元在链中形成规则的堆叠,并通过短的S⋯S接触进一步横向相互作用。对配体2和配合物3的循环伏安法测量表明这些多功能前体具有优异的给电子性能。

Bis- and tetrakis(triphenylstannyl)tetrathiafulvalenes were prepared from the corresponding lithio-derivatives and chlorotriphenyltin, and their structures were determined by X-ray analysis. Their absorption maxima in the electronic spectrum showed a bathochromic shift. Their redox potentials shifted only a little to a lower region. The charge-transfer complex of the tetra-substituted derivative with
由相应的硫代衍生物和氯代三苯基锡制备了双(三苯基锡烷基)和四(三苯基锡烷基)四硫富瓦烯,并通过X射线分析确定了它们的结构。它们在电子光谱中的吸收最大值显示出红移。它们的氧化还原电势仅转移到较低的区域。分离了四取代衍生物与TCNQ的电荷转移络合物。双(三甲基锡烷基)四硫富瓦烯不与(η- Cp)(CO)2 FeI反应,与(COD)PtCl 2反应,然后添加三丁基膦,得到复杂的混合物,由该混合物可以得到(C 2 H 2 S 2)铂(PBu 3)2分离产率低。通过X射线衍射确认了结构。还报道了方便的四硫富瓦烯和四碘四硫富瓦烯的制备方法。
TetrathiafulvaleneBenzothiadiazoles as Redox-Tunable Donor-Acceptor Systems: Synthesis and Photophysical Study
Electrochemical and photophysical analysis of new donor–acceptorsystems 2 and 3, in which a benzothiadiazole (BTD) unit is covalently linked to a tetrathiafulvalene (TTF) core, have verified that the lowest excited state can be ascribed to an intramolecular‐charge‐transfer (ICT) π(TTF)→π*(benzothiadiazole) transition. Owing to better overlap of the HOMO and LUMO in the fused scaffold of compound 3
Bis(thiomethyl)- and bis(thiohexyl)-tetrathiafulvalene-bromo-benzothiadiazoles, containing electron donor tetrathiafulvalene (TTF) and electron acceptor benzothiadiazole (BTD) units, have been prepared by Stille coupling reactions between the TTF-SnMe3 precursors and BTD-Br2. In another series of experiments, TTF-acetylene-BTD compounds have been synthesized by Sonogashira coupling between either TTF-acetylenes

ascribed to the intramolecular chargetransfer (ICT) π(TTF)→π*(TZ) transition. The tris(TTF) compound [(SMe)2TTF]3-TZ shows fluorescence when excited in the ICT band, and the emission is quenched upon oxidation. The radical cations TTF+• are easily observed in all of the cases through chemical and electrochemical oxidation by steady-state absorption experiments. In the case of [(SMe)2TTF]3-TZ, a low energy
