Two molecules containing two 2,5-diamido,3,4-dichloropyrrole units linked via 1,3- or 1,4-substituted benzene rings have been synthesized. The pyrrole groups in these compounds deprotonate in the presence of tetrabutylammonium fluoride and form pyrrole anion dimers via NH...N- hydrogen bonds. This dimerization process results in the formation of polyanionic chains linked via an unusual "orthogonal"
已经合成了包含两个 2,5-二酰氨基,3,4-二氯吡咯单元的两个分子,这些单元通过 1,3-或 1,4-取代的苯环连接。这些化合物中的吡咯基团在四丁基氟化铵的存在下去质子化,并通过 NH...N- 氢键形成吡咯阴离子二聚体。这种二聚化过程导致形成通过不寻常的“正交”氢键阵列连接的聚阴离子链。
