stronger acceptor than tetracyanoquinodimethane (TCNQ, E1⁄21 0.17 V vs. SCE). Both 1:1 and 2:1 salts, (Et4N)(OCNAQ) and (Et4N)2(OCNAQ), were obtained from reactions of Et4NI with potassium and lithium salts of OCNAQ, respectively. The X-ray crystal analyses of these salts indicate that the TCNQ moieties are boat-shaped bent to opposite directions. With the 1:1 salt, which behaves as a semiconductor (4...
合成标题化合物(OCNAQ)。1,2,3,4,5,6,7,8-八氢蒽与 N-溴代琥珀酰亚胺 (NBS) 在回流 CCl4 中使用 100-W 灯泡在辐射下处理,然后用过量的 NaCH(CN)2 进行二氰甲基化Me2SO 得到 1,4,5,8-四(二氰基甲基)衍生物的异构混合物。通过重复连续的溴化-脱溴化氢程序使混合物经受20%总产率的OCNAQ。OCNAQ 的循环伏安图表现出四个氧化还原波(E1⁄21 0.26、E1⁄22 0.05、E1⁄23 -0.44 和 E1⁄24 -0.53 V vs. MeCN 中的 SCE),表明 OCNAQ 是比四氰基醌二甲烷更强的受体( TCNQ,E1⁄21 0.17 V 与 SCE)。1:1 和 2:1 盐,(Et4N)(OCNAQ) 和 (Et4N)2(OCNAQ),分别从 Et4NI 与 OCNAQ 的钾盐和锂盐的反应中获得。这些盐的 X 射线晶体分析表明
