资源简介：
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” hydrogen-bonding array.
