A series of meso-thienyl-substituted porphyrins with different porphyrin cores such as N3S, N2S2 and N3O were synthesized and characterized. The thienyl groups at the meso-carbon atoms change the electronic properties of the porphyrin ring. The X-ray structure solved for the N2S2 porphyrin with four meso-thienyl groups showed supramolecular assembly formation in the solid state due to C−H···N hydrogen
合成并表征了一系列具有不同卟啉核心如 N3S、N2S2 和 N3O 的内消旋噻吩基取代的卟啉。中间碳原子上的噻吩基改变了卟啉环的电子特性。具有四个中噻吩基的 N2S2 卟啉的 X 射线结构显示出固态超分子组装形成,这是由于一个卟啉环的中噻吩基的 CH 基团与另一个卟啉环的吡咯N原子。具有两个内消旋噻吩基和两个内消旋芳基的 N3S 卟啉的 X 射线分析没有显示任何超分子组装在固态下的形成。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
