A series of non-aromatic anthripentaphyrins containing an anthracene unit, two thiophenes, and two pyrrole rings as a part of a macrocyclic framework connected via three -carbons were synthesized. The crystal structure of one of the anthripentaphyrins revealed that the two thiophene rings were in an inverted orientation, and the macrocycle adopts a nonplanar Z-like ruffled structure. These anthriporphyrinoids act as dienes and undergo Diels-Alder reaction with dienophiles to form stable non-aromatic Diels-Alder adducts.
一系列非芳香性的蒽并五氮杂卟啉包含一个蒽单元、两个噻吩环和两个吡咯环作为大环框架的一部分，通过三个碳原子连接。其中一个蒽并五氮杂卟啉的晶体结构表明，两个噻吩环处于倒置取向，大环采用非平面 Z 型褶皱结构。这些蒽并卟啉类化合物作为二烯，与亲二烯体发生 Diels-Alder 反应，形成稳定的非芳香性 Diels-Alder 加合物。
