21,23-Dithiaporphyrins and 21-monothiaporphyrins with propane-1,3-diyldioxy and its derivatives at the β-thiophene carbons were synthesized and characterized. The cyclic substituents introduced at the β-thiophene carbons altered the electronic properties of the porphyrins. The X-ray structure for 2,3-bis(2,2-dibenzylpropane-1,3-diyldioxy) substituted 21-monothiaporphyrin showed a more planar structure compared to the saddle shaped structure reported for β-unsubstituted 21-monothiaporphyrins.
合成并表征了21,23-二硫卟啉和21-单硫卟啉,这些化合物在β-噻吩碳原子处引入了丙烷-1,3-二醇氧和其衍生物。引入的环状取代基改变了卟啉的电子性质。2,3-双(2,2-二苄基丙烷-1,3-二醇氧)取代的21-单硫卟啉的X射线结构显示出比已经报道的β-未取代21-单硫卟啉的鞍形结构更平面。
