  Syntheses, Structure and Conducting Properties of Halogenated Ethylenedioxytetrathiafulvalenes

  摘要：

  4,5-Diiodo-, 4,5-dibromo-, and 4,5-dichloro-4',5'-ethylenedioxytetra-thiafulvalenes (EDO-TTFI2, EDO-TTFBr2, and EDO-TTFCl2) were synthesized in moderate to good yields by the two routes. The first route contains the reaction of EDO-TTF with LDA, followed by quenching with halogenated reagents, and the second route consists of the P(OR)(3)-mediated cross-coupling of 4,5-dihalogenated 1,3-dithiole-2-ones with 4,5-ethylenedioxy-1,3-dithiole-2-thione. The structures of EDO-TTFI2 and EDO-TTFCl2 were determined by X-Ray analysis. The radical-cation salts derived from EDO-TTFI2, EDO-TTFBr2, and EDO-TTFCl2 show high conductivities, although these compounds contain electron-withdrawing halogens as the substituent.

  organic superconductor (TEA)(HEDO-TTF-dc)2·2(H2C2O4) (H2EDO-TTF-dc = ethylenedioxy-tetrathiafulvalene dicarboxylic acids) with an onset TC of 4.0 K, was successfully obtained using oxalic acid and HEDO-TTF-dc anion donor. The crystal structure analysis indicated that strong π–π overlaps and very strong intra- and inter-molecular hydrogen-bonding interactions exist between the HEDO-TTF-dc anion donors

  一种新的有机超导体 (TEA)(HEDO-TTF-dc) 2 ·2(H 2 C 2 O 4 ) (H 2 EDO-TTF-dc = 亚乙基二氧基-四硫富瓦烯二羧酸)，起始T C为 4.0 K，是使用草酸和 HEDO-TTF-dc 阴离子供体成功获得。晶体结构分析表明，HEDO-TTF-dc 阴离子供体和草酸分子之间存在强烈的 π-π 重叠和非常强的分子内和分子间氢键相互作用。
