Cyclic voltammetry of derivative 7 in acetonitrile
exhibits two reversible oxidation waves, E1:2(1)0.49 V
and E1:2(2)0.76 V (versus Ag:AgCl), almost identical
to the values obtained for dimethylthio-TTF (E1:2(1)
0.45 V; E1:2(2)0.76 V). The structures of derivatives
3, 4 and 7 were determined by X-ray diffraction
measurements7 of single crystals. The crystal structure
of 7 (Fig. 1) shows no intermolecular interactions,
although the stack is segregated along a diagonal axis.
The interplanar distances between the planes of pyridine–
pyridine and TTF–TTF are longer than 5.7 A, .
Alkylation of 7 is facile using 3–4-fold excess of methyl
iodide at room temperature in acetonitrile or acetone,
from which product 8 precipitates as black crystals. Salt
8 exhibits an ICT absorption band at lmax572 nm in
ethanol, which does not correspond to any of the TTF
or pyridinium moieties, and obeys the Beer–Lambert

在acetonitrile中循环的伏安法的派生物7展示几乎和为 dimethylthio-TTF得到价值观完全相同二可翻转氧化波 ,E1:2(1)0.49 V和E1:2(2)0.76 V(对Ag:AgCl)E1:2(1)0.45 V;E1:2(2)0.76 V.派生物3,4和7的结构被单一的水晶的X光衍射measurements7决心.虽然堆存在沿着一对角线的轴隔离,7的水晶结构((Fig. 1)展示没有分子间的相互作用.interplanar 与5.7 A相比更长pyridine?C吡啶和TTF?CTTF公亩的飞机之间的距离.Alkylation的7是易做到的使用3?C4- 褶印过多的在从8作为黑水晶促成哪一个产品acetonitrile金色丙酮中甲基碘化物阿特室温.Salt 8在lmax 572nm在朝派乙醇,其不与TTF或者pyridinium一半任何相符和守 Beer?CLambert法的展示一ICT吸收带.这个乐队的位置是有支付力受抚养者:一在DMSO解决方案((540 nm)中蓝移的和一在甲叉二氯((618 nm)中红移的被注意到.二可翻转氧化波被为这种化合物在更高潜力((E1:2(1)0.58 V和E1:2(2)0.81 V(对 Ag:AgCl))方面同意电子注意到接受取代基的本质.8的光化作用的小道具是和涉及trimethyl TTF赠送人unit8类似物相似和将其它地方被详细讨论.
