complementary porphyrin building blocks, it is possible to build various types of multi-porphyrin supramolecules with different spatial relationships in predefined geometries. The formation and properties of self-complementary dimers and a closed tetrameric square are presented as a basis of comparison to the latter system in the solid state. An X-ray structure of 5,10-bis(4-tert-butylphenyl)-15,20-bis(3,
两种醛,2,6-二乙酰氨基-4-甲酰吡啶 (7) 和 1-丁基-6-甲酰尿嘧啶 (11),用于合成五个吡啶基和四个尿酰基内消旋取代的卟啉。利用这些互补的卟啉构建模块,可以构建具有预定义几何形状的不同空间关系的各种类型的多卟啉超分子。提出了自互补二聚体和封闭四聚体的形成和性质,作为与后一种固态系统进行比较的基础。5,10-双(4-叔丁基苯基)-15,20-双(3,5-二乙酰氨基-4-吡啶基)卟啉的X射线结构证实了其分子结构,并揭示了由氢键介导的超分子组织水分子。
