The crystallization and the crystal and molecular structure of a very slightly soluble electrostatically interacting pair of porphyrins is described. The tetra-anion 5,10,15,20-tetrakis-(4-sulfonatophenyl)-21,23H-porphyrin [H2TPPSO3][Formula: see text] and the tetra-cation 5,10,15,20-tetra([Formula: see text]-methylpyridyl)21H,23H-porphyrin [H2TMePyP][Formula: see text] are found to form an alternating one-dimensional stack that is stabilized by electrostatic interactions between the porphyrin rings but also by [Formula: see text] interactions between all substituted phenyl rings in the ensemble. The resulting interactions between the porphyrins is exceptionally tight.

固态卟啉与带相反电荷的外围基团的相互作用

描述了极微溶的静电相互作用卟啉对的结晶以及晶体和分子结构。四阴离子 5,10,15,20-四-(4-磺基苯基)-21,23H-卟啉 [H2TPSO3][分子式：见正文]和四阳离子5,10,15,20-tetra([分子式：见正文]-甲基吡啶基)21H,23H-卟啉[H2TMePyP][式：参见文本]被发现形成交替的一维堆叠，该堆叠通过卟啉环之间的静电相互作用以及整体中所有取代的苯环之间的[式：参见文本]相互作用来稳定。由此产生的卟啉之间的相互作用异常紧密。
